0.00001 on overall gear ratio) depending on the user selected constraints (unequal gear ratio for every stage, noninteger gear ratio e.g.). Dimensional design is determined by considering bending stress, pitting stress, and involute interference constraints. These steps are carried out iteratively until a desirable solution is acquired. The necessary parameters for configuration design such as number of teeth, module, addendum modification coefficient, are selected from previously determined gear pairs that satisfies the constraints by user interaction considering the performance criterion from the developed program. The positions of gears and shafts are determined automatically in order to keep the volume of gearbox as minimum while satisfying the nonlinear spatial constraints (center distance constraint for proper meshing of gear pairs, face distance constraint for proper assembly of pinion and gear having same shaft, gear interference constraint for preventing interferences between gears, shaft interference constraint for preventing interferences between gears and shafts) by using DLL (Dynamic Link Library) technology of Lingo 8.0 optimization software together with Visual Basic 6.0. If shaft interference constraint is removed then cantilevered mounting of gear pairs would also be possible, otherwise the gears should be mounted between bearings. Visual output of assembly is made by using Autodesk Inventor 7.0, automatically by the program.

Повний текст джерелаIn the frame of this Master Thesis a dynamic single-track-model of a hybrid electric vehicle was developed. The model comprises basic operation modes such as electric, conventional and hybrid driving, recuperation of braking energy and engine start-stop. It allows to scale the split of the propulsion between the combustion and electric engine. A further fundamental com- ponent is the model of a friction disc clutch, enabling the simulation of torque transmission of a slipping clutch during the vehicle start and the upspeeding of the combustion engine through the electric engine. The program offers three driving cycles for simulation (NEDC, WLTC, FTP- 75). Fuel consumption, CO2-emissions, propulsion and recuperation work of the combustion engine, electric engine and the wheels are provided as output variables as well as the required and recuperated electric energy. Furthermore several relevant variables are displayed in their progress over time. The model was validated against real vehicle data showing a good corre- lation regarding acceleration, maximum speed and fuel consumption

This thesis presents an analytical methodology on the NC data generationfor maching of spur gear meshed with spur rack on 3-axis machine tools, andautomation measurement of the spur gear on coordinate measuring machine. Theability function of the machine tool and the coordinate measuring machine arederived by the Denavit-Hartenberg notation. The desired cutter and probe locations are also derived by the Denavit-Hartenberg notation. The cutting NCdata equations are obtained by solving the link variables of the machine tool through equations of its ability function and the desired cutter location matrix. The measuring NC data equations are obtained by solving the link variables of the coordinate measuring machine througt equations of its abilityfunction and the desired probe location matrix. To verify the developed methodology, this gear is machined on a 3-axis machine tool, and measured on a coordinate measuring machine then. The measuring data will be localized through a program designed to get a better measuring result. This methodology is a general one and is applicable for various gear manufactures and measurements. It also combine the activities of gear design, manufacturing, and measurement.

Shifted gears are generated by standard gear generating tools with gear pitch circle intersect or away from the tool pitch line. Therefore, a pair of mating pinion and gear has different addendum/dedendum. Shifted gears may be employed in one of the occasions, (a) to avoid undercutting, (b) to obtain lager contact ratio, (c) to fit specific center distance in a gear train, and (d) to increase the tooth root strength. However, when gear engineers try to improve one factor by the using of shifted gears, usually, other factors become worse. So, tedious try-and-error procedures must be taken in the design of shifted gears to meet all the demands. This thesis discusses the general procedures of designing shifted spur gears, and provides a Microsoft ExcelÒ code to perform the tedious try-and-error task effectively and efficiently. This thesis also provide a method to analyze shifted spur gear deformation by using of Timoshenko Beam Theory, since the traditional Lewis Method for gear stress analysis is not suitable for analyzing shifted gear strength. Examples for improving gear performance through properly choosing a shifting coefficient are shown in the article too.

With an increasing demand for high performance machinery, dynamic analysis for gears has become important. Instead of discrete mass-spring models, this study presents a dynamic stiffness method to analyze spur gear dynamics. The dynamic responses of single gears and gear pairs are investigated. This continuum approach takes into account time-varying stiffness and mass matrices due to moving meshing points. Firstly, using a dynamic stiffness method, dynamic analysis for rotating nonuniform cross-section Euler beams is carried out. Longitudinally stiffening effect is taken into account by including a geometrically nonlinear term. The dynamic stiffness of a beam element is formulated using power series. Tip deformations of the beams are calculated. In contrast to the finite element method that has to refine the element mesh, accurate dynamic response can be obtained with only few elements and few modes in the dynamic stiffness method. The dynamic stiffness method for a Timoshenko beam is further developed and applied to spur gear dynamic analysis. Firstly, quadratic polynomials are used to represent profiles of the nonuniform cross-section beam elements for the gear blank and tooth. Then, the dynamic stiffness matrix of a Timoshenko beam element is derived. Next, assemble the dynamic stiffness matrices of the beam elements and a nonlinear Hertzian contact stiffness to form the dynamic stiffness matrix of the gear system. Finally, tip deformations and fillet strains of gears are calculated by performing modal analysis and the Runge-Kutta method. In experiment, tip deformations and fillet stains are respectively obtained using CCD image processing and a strain gauge. Experimental results serve to verify calculation results by the proposed method. The final part of this study investigates the effect of the centrifugal force arising from the gear rotation on gear dynamics. In addition, this study also examines influences of gear parameters including the correction factor, backlash, and nonstandard center distance on gear dynamics. Fillet strains of a gear pair are calculated using a multi-tooth pair model to account for multi-tooth pairs in contact.

Recently, the extreme climate types occur frequently under the effect of climate change, causing more frequent flooding. The main channels change significantly in Taiwan because of the rapid flows and steep slope gradient carrying high sediment load. As a result, it causes serious disasters such as scouring of the river bed around the levee foundation. Therefore, this study develops a new type of protection works, the water-permeable ring column spur dikes, to enhance the security of levee foundation. The results for various shapes and axis inclination of the pervious spur dikes will compared with those for the traditional impervious spur dikes. Based on the experiments, the scour characteristics, and the optimal allocation of the spur dikes were explored and can be applied to the relevant engineering units. The results show that in general the position of maximum scour depth occurs near the head of spur dike, and it moves further away from the levee as the axis inclination increases. The maximum scour depth of the ring column spur dike is usually smaller than the traditional one. The permeability and flexibility of ring column spur dike can promote flow turbulence and dissipate the energy of downflow, and thus restrain the development of scour hole around the spur dike. Comprehensive consideration of the safety of spur dike and levee foundation reveals that the type Ⅲ, with 1/10 axis inclination, of water-permeable ring column spur dike is the optimal type among the experimental conditions conducted in this study. The optimal allocation of spur dike can reduce 50% of the scour depth reduction rate and 73.6% of the scour holes at the dike head. It can effectively reduce spur dikes scour depth, and move the position of maximum scour depth away from the levee and increase the safety of levee foundation.

The stress analysis with CAD/CAE software is generally used nowadays for the contact analysis of a gear pair. The software package ANSYS® is chosen as the analytic platform to analyze the contact and bending stresses of a spur gear pair in this thesis. The discrete tooth profile data is first processed by the proposed points-added and points-deleted methods. The gear model and ANSYS® scripts are built by the Mathematica® program, and the nodes and meshes of the spur gears are auto-generated in the preprocessing software HyperMesh®. The simulated results of the contact and bending stresses calculated in ANSYS® are compared with the theoretical experience formulas to verify the validity of the analytic model. In the numerical examples, the pressure angle and the tooth height of a spur gear pair are varied to discuss their influence upon the gear tooth strength. All in all, the proposed procedure in this thesis can provide an exact tooth strength analysis for a spur gear pair.

The purpose of this study is to apply the finite element method to the contact stress analysis of spur gears. The ANSYS APDL code is written to develop finite element model and perform contact stress analysis. Different contact algorithms used in frictionless/friction contact and bending stress analysis in spur gear are also discussed. In order to verify the validity of the method of contact stresses analysis, the finite element results are first compared to the analytical solution of a cylinder in contact with a half-plane. The results show the penalty function algorithm can generate the solutions in better agreement with the analytical solution. The finite element analysis is also applied to study the effect to gear parameter on the contact stresses between a pair of gear tooth and bending stresses of gear root. The results show the contact stress at gear surface and bending stress of the gear root decrease with an increasing pressure angle.

Taiwan often encounters heavy rains in the mountains due to frequent typhoons, which makes the rivers flow directly into the river, and the Spur dike is one of the ways to solve the crisis of water flow. In this paper, the construction case is located in the spur dike of the Six Turtle No. 1 Bridge. This is because the typhoon in Kong-rey has caused severe changes in the river channel, resulting in the entire spur dike foundation being emptied by the river, resulting in dikes. The collapse of the embankment collapsed, so in order to relieve the strength of the river, strengthen apron of the spur dike, and use the wave block to block the strength of the river to reduce the force of the spur. In view of this, this paper applies the engineering legislation to the construction process, closely links the engineering regulations with the construction process, and properly manages the quality to ensure the smooth completion of the project and the consolidation of the embankment, so that the people’s property can be protected and the nearby Residents need no fear of flooding beasts.
