Abstract:

In order to improve ability of walking and crossing the barriers , increase the carrying capacity, and enhance its popularity and adaptability, a novel lower limb bionic leg is presented based on 3-UPS parallel mechanism, which has the characteristics of movement flexible and strong adaptability. It is very important analysis to statics of lower limb bionic leg. Firstly, statics equation of the lower limb bionic leg of driving force and output force is established based on virtual work principle. Secondly, static performance evaluation index is defined and the evaluation index distribution map is drawn. The relationship between the structure parameters and the static performance evaluation indexes is analyzed, obtained the influence of structure parameters on the static performance evaluation index, and a set of reasonable structural parameters is selected. The circum-radius of moving platform is 50mm, the circum-radius of the static platform is 150mm, the moving platform angle and static platform angle are equal to 60°, the lower limb bionic leg has the best load carrying capacity. Thirdly, the lower limb bionic leg is designed based on statics analysis and structure parameters optimization. Analysis results show that the lower limb bionic leg has good static transmission performance at the initial position, and the static transmission performance decreases with increasing turning workspace. The static transmission performance decreases with z axle displacement increasing. The analysis results laid a foundation for further analysis and research of the lower limb bionic leg.

Abstract:

This study compared the effects of dynamic and static core training programs on core stability tests and Stork balance performance in soccer players. A Static (n = 14, 18,21±1,81) and Dynamic (n = 13, 17,31±0,63) training groups performed three 30 min sessions per week for eight weeks meanwhile attended routine soccer training sessions with a control group (n = 11, 17,73±1,27). Effects of different core training regimes were compared after eight weeks with two-factor variance analysis (condition X time) for related measures. Two experiment groups improved dynamic and static core stabilization test scores, while control group did not change. Core stabilization tests showed that the improvements of experiment groups affected by the movement specifity and Static group increased static test scores (plank 23,8% - back isometric 28,9% - leg raise 15,6%) while Dynamic group increased mostly the dynamic test scores (sit-up 21,2%, push up 16,2%). For Stork balance, both experiment groups improved the test scores between %18 and %67. While the Static group increased the duration of Stork test on both feet more than the Dynamic group, this difference was statistically significant only for non-dominant foot in intergroup analysis. The static structure of the Stork test may explain the significant improvement in static core group. Results indicate that the positive effect of core training on core stability may improve balance and static core training may be more effective for static balance tests.Extended English abstract is in the end of PDF (TURKISH) file. ÖzetBu çalışmanın amacı, 8 haftalık statik ve dinamik core egzersizlerin futbolcularda core stabilizasyon ve Stork denge performansı üzerine etkisini karşılaştırmaktır. Toplam 38 sporcu (17,75±1,36) Dinamik (n=13, 17,31±0,63), Statik (n=14, 18,21±1,81) ve Kontrol (n=11, 17,73±1,27) grupları olarak üç gruba ayrıldı. Statik ve Dinamik egzersiz grupları 8 hafta, haftada 3 gün, günde yaklaşık 30 dakika statik ya da dinamik egzersizler uygularken, buna karşın kontrol grubu yalnızca futbol antrenmanları gerçekleştirdi. Verilerin analizinde ilişkili ölçümler için iki faktörlü varyans analizi kullanıldı. Tüm core stabilizasyon testlerinde deney grupları anlamlı gelişme görüldü. Kontrol grubunda değişme görülmedi. Gelişmenin hareketin spesifikliğinden etkilendiği, Statik grubun statik test skorlarını daha fazla arttırdığı (plank 23,8% - sırt izometrik 28,9%- bacak kaldırma 15,6%), Dinamik grubun ise dinamik testlerde skorları daha fazla arttırdığı (şınav 16,2% - mekik 21,2%) görüldü. Benzer şekilde, iki deney grubu Stork denge testinde her iki ayak için denge süresini % 18 ile% 67 arasında artırdı. Ama kontrol grubu değişmedi. Statik grup her iki ayak içinde dengede kalma süresini Dinamik gruba göre daha fazla arttırırken, gruplar arası analizde non-dominant ayak ölçümünde bu farklılık istatistiksel olarak anlamlılık g. Denge ölçümünün statik yapıda olması, Statik gruptaki yüksek gelişimi açıklayabilir. Sonuç olarak; dinamik ve statik core egzersizler ile artan core stabilizasyonun statik denge üzerinde olumlu etkisi olduğu tespit edildi. Ancak statik core çalışmalarının statik denge performansı için daha etkili olduğu söylenebilir.

Moreover the objective optimal function was established basing on the global torque performance evaluation index, and the relation of the objective optimal function and the global torque performance evaluation index were analyzed. By use of fully automatic searching method, the optimal structural parameter ranges of the bionic robot hip joint were obtained. Analysis results show that the bionic robot hip joint has good static transmission performance at initial position, and the static transmission performance is decreased with increasing the workspace. Finally, using a set of optimal structural sizes parameters, a novel bionic robot hip joint was designed, which established the theoretical foundation for the bionic robot design and apply.

Abstract:

As key factor of numerical simulation for gear strength, namely determination of effective loads between meshing teeth profiles, their numerical calculation principles of static and dynamic finite element methods are analyzed according to the loads on gear teeth. The static analysis of gear strength can be classified to effective statics and static contact analysis, and the numerical simulation method for face distribution as the rule of Hertz contact is advanced. The differences between static and dynamic contact and their influences in results are researched. Compared with the empirical formulas, the analytical results about bearing capacity of gear drive under different effective loads show: (1) As the sequence of concentrated force, linear distribution force, face distribution force as the rule of Hertz contact, static contact analysis, the accuracy and reliability of calculating results under different effective loads are improved, especially the results from face distribution and static contact being very close. (2) Dynamic contact analysis can be used to simulated the effect well. The above studies could be referenced to calculation in bearing capacity of gear drive.

Abstract:

The most common structural load test that has been widely used is the static load test. An alternative to the structural load test is dynamic load test. Dynamic testing is a test carried out to determine level of structural stiffness or structural elements stiffness in the form of natural frequencies, while the static load test is intended to obtain responses of static loading from the structure in the form of deflection. The discussion will emphasize the correlation between static load test and dynamic load test. To correlate the static load test with the vibration test, a reference or value that comes from modeling or theoretical analysis is needed. Structural modeling is carried out to obtain the theoretical natural frequency and the theoretical deflection which will then be compared with the natural frequency of the vibration test (dynamic). If the frequency of the test results and the theoretical frequency are compared to the theoretical deflection, the prediction of the test deflection will be obtained. The correlation between the predicted deflection of the test and deflection of the static load test is quite close with a difference of less than 12%. Judging from the above correlation, periodic inspections of the tested structures can be considered for vibration testing only. The types of structures reviewed are simple span steel bridge structure, simple span + link slab steel bridge structure and continuous span steel bridge structure. Keywords: modeling; natural frequencies; vibration testing; static load test AbstrakUji beban struktur yang umum dan sudah banyak dilakukan adalah uji beban statik. Alternatif lain dari uji beban adalah dengan melakukan pengujian vibrasi (dinamik) pada struktur. Pengujian vibrasi (dinamik) dilakukan untuk mengetahui tingkat kekakuan struktur atau elemen struktur berupa frekuensi alami, sedangkan uji beban statik dimaksudkan untuk mendapatkan respons hasil pembebanan statik dari struktur berupa lendutan. Pembahasan akan menekankan kepada korelasi antara uji beban statik dan uji beban vibrasi (dinamik). Untuk mengkorelasikan pengujian beban statik terhadap pengujian vibrasi (dinamik) diperlukan suatu acuan atau nilai yang berasal dari analisa pemodelan atau teoritis. Pemodelan struktur dilakukan untuk mendapatkan frekuensi alami secara teoritis dan lendutan teoritis yang kemudian akan dibandingkan dengan frekuensi alami hasil uji vibrasi (dinamik). Jika frekuensi hasil uji dan frekuensi teoritis dibandingkan terhadap lendutan teoritis maka akan didapatkan prediksi lendutan uji. Hasil korelasi antara prediksi lendutan uji terhadap lendutan uji beban statik cukup mendekati dengan perbedaan kurang dari 12%. Dilihat dari korelasi diatas, maka untuk pemeriksaan berkala pada struktur yang telah diuji dapat dipertimbangkan untuk dilakukan pengujian vibrasi saja. Jenis struktur yang ditinjau adalah struktur jembatan baja simple span, simple span + link slab dan continuous span.

Abstract:

Physicochemical properties of cellulose produced by local bacterial strain Gluconacetobacter xylinus KRE-65 by static and agitated fermentation methods was studied. Cellulose production by G. xylinus KRE-65 was carried out in coconut base medium with static and agitated fermentation methods. The dry weight, morphological and physicochemicalproperties of bacterial cellulose were compared based on SEM, XRD and FTIR analyses. The results showed that the G. xylinus KRE 65 in the static fermentation produced cellulose higher than agitated fermentation. Static fermentation method produced bacterial cellulose in the sheets form, while agitated fermentation produced fragmented cellulose with predominantly spherical shape. The observation of the surface structure of bacterial cellulose by SEM showed that the static fermentation method generated woven densely cellulose microfibrils, while agitated fermentation significantly changed the surface structure, namely woven microfibrils become more loose with formed larger and higher number of pores. The degree of crystallinity of bacterial cellulose by XRD analysis in static fermentation was 91%, agitated fermentation at 100 rpm was 73% and agitated fermentation at 150 rpm was 72%. FTIR spectra indicated that the pellicles produced by G. xylinus KRE 65 with static and agitated fermentation were found as cellulose. Cellulose produced from both fermentation methods showed different physicochemical properties, therefore they can be applied for different purposes in accordingly.Keywords: Gluconacetobacter xylinus, bacterial cellulose, static fermentation, agitated fermentation ABSTRAKSifat fisikokimiawi selulosa yang dihasilkan oleh strain lokal bakteri Gluconacetobacter xylinus KRE-65 dengan metode fermentasi statis dan agitatif telah diteliti.

Selulosa yang dihasilkan selanjutnya dibandingkan beratkering, bentuk morfologi dan sifat fisikokimiawinya menggunakan metode SEM, XRD dan FTIR. Hasil penelitian menunjukkan bahwa G. xylinus KRE 65 menghasilkan selulosa lebih tinggi pada metode fermentasi statis dibandingkan fermentasi agitatif. Metode fermentasi statis menghasilkan selulosa bakteri yang berbentuk lembaran sedangkan fermentasi agitatif menghasilkan selulosa yang terpecah-pecah dengan bentuk dominan bulat. Pengamatan struktur permukaan selulosa bakteri dengan SEM memperlihatkan bahwa metode fermentasi statis menghasilkan selulosadengan anyaman mikrofibril yang padat, sedangkan fermentasi agitatif menyebabkan terjadinya perubahan struktur permukaan yaitu melonggarnya anyaman mikrofibril dan terbentuknya pori-pori yang lebih besar dan lebih banyak.

Abstract:

Static correction is an essential step in seismic processing and it has an effect on the later steps of seismic processing, including velocity analysis, data stacking, and seismic inversion. During seismic data acquisition, a receiving point usually sets a geophone several times to receive the seismic data. The same geophone cannot be set at the same receiving point every time. If the geophones have different delay time, then the common receiving-point gather (CRG) will have multiple receiver statics. However, the receiver statics of a CRG are considered the same in conventional static correction. In this paper, based on common attitude gather (CAG), a novel static correction method is proposed to analyze the receiver statics of a CRG. Attitude indicates the tilt angles of the three components of a geophone. According to the different attitudes of geophones, CRG can be divided into multiple CAGs. When the difference technique is used to the novel method and the conventional method, the statics are analyzed with CAGs and CRGs, respectively. A field example demonstrates that the proposed method cannot only enhance the continuity of the event in the shot gather, but also smooth the gaps of the event in the CRG. The results suggest that the proposed method can eliminate the effect of differences in delay time of geophones on static correction.

Abstract:

Conventionally, the influence of guy wire and wind load on derrick was often ignored in the static strength analysis of derrick of truck-mounted workover rig, it does not accord with the actual working conditions. This paper made the finite element analysis for one derrick of Truck-mounted workover rig through ABAQUS software. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, under different static hock load and wind load, determining the weakest position of derrick. Truck-mounted workover rigs are widely used in the filed of workover and drilling operation, due to their characteristic of power maneuverability and convenient to use. Derrick is the mainly working part of workover rig, as well as the weak links of workover. In order to guarantee relatively high security performance, we should accurately make simulated calculation for carrying capacity of derrick in the process of designing. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, by using the ABAQUS FEM system, apply for statics analysis of derrick under different static hock load and wind load.

Abstract:

Aktivitas masyarakat tidak terlepas dari peran teknologi. Internet selalu berkembang dan sudah dapat diakses oleh seluruh orang, hampir seluruh pekerjaan menggunakan internet untuk mengakses apapun. Dengan internet kita dapat saling terhubung antar perangkat dan bisa mengakses secara luas, seperti antar gedung yang saling terhubung dengan pembagian ip dalam sebuah jaringan.Terdapat dua teknik peroutingan yang akan dibandingkan, yaitu secara statis dan dinamis dengan teknik RIP (Routing Information Protocol) dan menggunakan topologi ring untuk pertukaran data nya. Kedua routing akan dibandingkan untuk mengetahui troughput, delay, dan packet loss dengan keadaan sibuk dan tidak sibuk, tujuannya adalah ntuk mengetahui kinerja routing statis dan dinamis dengan teknik RIP (Routing Information Protocol). FTP (File Transfer Protocol) bisa digunakan untuk mengunduh atau mengunggah file dari pc ke server, mempunyai besaran sendiri dan bisa digunakan unuk mengakses troughput. Untuk mendapatkan hasil FTP bisa melalui traffic generator pada comand prompt. Hasil yang diperoleh untuk delay pada kedua routing bagus, karena rerata <150 ms. Routing static pada traffic tidak sibuk lebih rendah nilai delay, sedangkan pada routing static lebih rendah nilai delay pada traffic sibuk. Pada traffic sibuk dalam pada kedua router tidak memiliki nilai packetloss, sedangkan pada traffic tidak sibuk, routing dynamic dengan teknik rip mempunyai nilai packetloss lebih rendah dibanding routing static. Nilai throughput pada traffic tidak sibuk routing dynamic dengan teknik RIP lebih tinggi dibanding dengan routing static, sedangkan routing static mempunyai rerata nilai throughput pada traffic sibuk lebih tinggi dibanding routing rip

Abstract:

In this paper, the static mechanical properties of a spherical magnetically suspending rotor are studied based on the finite element analysis method. The structure of the spherical magnetically suspending rotor is designed. The characteristics of the spherical magnetically suspending rotor are analysed and the necessity of static analysis is pointed out. The main content and general flow of statics analysis are discussed. The two working modes (GUI mode and command flow mode based on APDL) of the finite element software ANSYS are compared and analysed. Then the finite element model of the spherical magnetically suspending rotor is established by the command flow method, and the detailed modelling steps are given. On this basis, the static characteristics of the spherical magnetically suspending rotor are simulated and analysed. The simulation results show that the maximum equivalent stress and rigid body displacement of the rotor are within the safety threshold at a design speed of 10000rpm.

Abstract:

The classic forms of disc crusher disintegration simulations are faced using methods that associate their analysis to the stochastic nature of the process. This paper introduces a method that can solve the disc crusher disintegration simulation with a partially deterministic manner. The paper presents the result of the thrust force and the consumed power of disc crushers which is estimated by a static analysis of forces that interact within the discs (fixed and mobile). This methodology uses the calculation of forces and directions involved in the process of particle fragmentation. The fragmented material is characterized. The fragmentation process is simulated with the help of the computer programme to finally estimate the consumed power. For comparison purposes, two types of disc crushers are designed to determine the capability of the method after assessing the results.

Abstract:

In this paper, the finite element method is used to analyze the static response of the functionally graded porous (FGP) sandwich beams subjected to uniformly distributed loads along the beam span. The core of the beam is made up of functionally graded porous material while the top and bottom layers are made up of isotropic homogenous materials. Uniform distribution and symmetric distribution of pores are used as two different types of porous material. Shear deformation is considered in the analysis by utilizing BEAM189 in ANSYS which is a finite element package program. This element is based on the first-order shear deformation theory. The influence of porosity coefficient, boundary conditions, and type of the porous material on the static response of the considered structures is presented in detail. The results demonstrate that the porosity coefficient has an important impact on the static response of the FGP sandwich beams.

Pembebanan gempa dengan menggunakan metode analisis static equivalent dan analisis dynamic time history, memiliki perubahan pembebanan yang sangat mendasar diantara kedua metode. Pada penelitian sebelumnya menyebutkan bahwa “perubahan mendasar terjadi pada struktur 5 dan 10 tingkat”. Penelitian ini bertujuan menganalisis perbedaan pembebanan, menganalisis perubahan pembebanan yang sangat mendasar dan menganalisis metode yang cocok dalam perencanaan pembebanan pada bangunan dengan rentan 5, 6, 7, 8, 9 dan 10 tingkat. Studi kasus dilakukan menggunakan data respons spectrum Kabupaten Garut dan time history El Centro 1940 (seismik frekuensi menengah). Fungsi bangunan sebagai hotel sebagai acuan untuk menentukan kategori risiko. Klasifikasi situs tanah keras dan menggunakan mutu beton yang digunakan fc’= 30 MPa. Untuk menghitung analisis statik ekivalen digunakan standar perhitungan SNI 1726-2019. Hasil penelitian menunjukkan bahwa perhitungan pembebanan gempa yang terjadi pada struktur 5 dan 6 lantai menggunakan analisis statik ekivalen dinilai akurat karena menghasilkan pembebanan gempa yang mendekati dengan hasil dari perhitungan analisis dinamik time history, tetapi dalam analisis ini pada struktur 7 lantai atau lebih untuk melakukan perhitungan pembebanan gempa lebih disarankan karena menghasilkan pembebanan yang jauh lebih besar dari perhitungan analisis statik ekivalen. Nilai gaya geser pada analisis statik ekivalen dinilai lebih linier peningkatannya dibandingkan dengan analisis dinamik time history.
