Abstract:
The object of research is hydrostatic processes in sliding bearings with several layers of lubricant. The task addressed was the influence of the structural and operational parameters of dual hydrostatic plain bearings on their static and dynamic characteristics. As a static characteristic, the bearing capacities of dual and conventional sleeve hydrostatic bearings were considered. When analyzing the dynamic characteristics, the amplitude-frequency characteristics were determined. They were obtained by calculation and as a result of experimental studies.

Abstract:
This study was initiated in view of the phenomenon that hydrostatic turntable rails are prone to scrape damage when the liquid hydrostatic turntable is running under fixed partial load. The existing bias-load hydrostatic turntable oil film bearing characteristics are mainly calculated by using the calculus integration method and CFD fluid simulation method. The calculating formula obtained by the calculus integration method is complex and inefficient. The CFD fluid simulation calculation method requires 3D modeling and meshing of the oil film, which is a tedious and time-consuming process and

Abstract:
To calculate the carrying capacity of spherical hydrostatic bearings, a numerical calculation model was presented. The influence law of dynamic pressure effect on the carrying characteristics of liquid hydrostatic spherical bearings is revealed. Under general working conditions, the dynamic pressure effect caused by the radial eccentricity of the bearing has little influence on the bearing load characteristics parameters; when the minimum width of the gap between the sealing edge is very small and the bearing rotational speed is high, the dynamic pressure effect is more obvious.

The results demonstrate that as the minimum width of the oil gap decreases, the maximum dynamic pressure increases non-linearly. Furthermor

Abstract:
In industrial practice greases are mainly used as lubricants in hydrodynamic plain bearings and roller bearings. The use in hydrostatic bearings is avoided due to the difficult controllability. One reason is the complex non-Newtonian flow behavior of greases. The motivation for this paper is the use of greases to increase the efficiency of hydrostatic bearings. The assumption is that the so-called yield stress of consistent greases can lead to self-sealing behavior in the bearing under stationary operation conditions.

In fluid power machinery hydrostatic bearings are frequently used, and a first approximation approach to design is determination of a balance ratio by analytical calculation of the hydrostatic pressure force. Usually this is performed assuming that the thermo-piezo-viscous property can be neglected. However, in applications as piston machines, where pressure in many cases exceeds 200 Bar, such assumption leads to considerable error in the balance ratio prediction, due to the piezo-viscous property of the lubricant.

The supplied amount of jacking oil is very small compared to the regular oil supply.

A computer simulation was implemented to assess thrust bearing and mechanical sealing functions of the fluid film between cylinder barrel and valve plate. A new algorithm was developed to facilitate simultaneous calculations of dynamic cylinder pressure, 3 degree-of-freedom barrel motions considering inertia effect, and fluid film pressure assuming full fluid film

Abstract:
This work presents a thin film flow model for analyzing the static and dynamic characteristics of centered, eccentric or misaligned tangential-against-rotation injection Lomakin bearings. The Lomakin bearing is a recent device intended for use in modern turbomachinery and having characteristics similar to hybrid bearings. It can be described as an ensemble of two opposing straight annular seals separated by a circumferential feeding groove. The fluid is supplied to the groove via orifice restrictors. Their tangential inclination generates an against-rotation circumferential flow in the groove

Abstract:
In this paper, loaded compression member of single-limb fire-curved equilateral double splicing T-shaped angle steel is compared with the calculation value of the bearing capacity of ordinary double-angle steel members in relevant domestic and foreign codes. When the slenderness ratio of members is large, the value obtained according to the steel structure design standard (GB 50017-2017) is closer to the test result. Based on the steel structure design standard (GB 50017-2017), the stability calculation method of axial compression members is presented in this paper. And based on the results of

SEISMIC PERFORMANCE OF SINGLE-LAYER SPHERICAL RETICULATED SHELLS CONSIDERING JOINT STIFFNESS AND BEARING CAPACITY. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/ijasc.2022.18.2.9.

Abstract:
Fabricated joints are gradually applied in architectural structures because of their advantages of good economy, high installation quality and efficiency. However, the mechanical properties of this kind of joint are semi-rigid differing from traditional rigid and hinged joints. Therefore, the performance of the structures with such joints is not clear, which greatly limits the wide application of fabricated joints. This paper presents the investigation on the seismic performance of the semi-rigid single-layer reticulated shell structure (SRSS) under earthquake load by numerical simulation and

Abstract:
Widely employed in enveloped structures, the metal-faced sandwich panel boasts thermal insulation, noise abatement, lightweight, and remarkable assembly efficiency. In this paper, a new type of profiled steel sheet and polyurethane sandwich slab (PSSPSS) was proposed. Through static load tests and numerical simulations, the flexural properties of the PSSPSS were studied, and the influence of individual geometric parameters on the flexural capacity of the structure was evaluated. The results of this analysis led to the derivation of the calculation formulas for the deflection and flexural beari

Abstract:
The Thread-fixed One-side Bolt (TOB), which utilizes internal threads in the bolt hole instead of a nut, enables installation from one side, thereby overcoming the challenge of connecting closed-section components, such as steel tube columns, which are not suitable for traditional bolt connections. This study establishes and validates a Finite Element Model (FEM) to investigate the mechanical performance of TOB connections under high temperature conditions. The results show that the wall thickness of the column has a significant influence on the performance of the connection; an increase in wa

Abstract:
The shear key is crucial to the overall mechanical performance of the structure. A new type of semi-rigid connector-flange folded web shear key was proposed to determine the effective unity of higher bearing capacity and deformation. A total of five groups of specimens were designed, and the push-out test method was used to evaluate the ultimate bearing capacity, bond-slip process, failure mode, and strain distribution of the new shear key. The results show that before sliding, the embedded effect of the concrete and shear key is significant, and it has a significant sliding stiffness. After s

BENDING CAPACITY OF COLD-FORMED THIN-WALLED STEEL TUBES INFILLED WITH GYPSUM. The Hong Kong Institute of Steel Construction, 2025. https://doi.org/10.18057/ijasc.2025.21.1.5.

Abstract:
Cold-formed thin-walled steel tubes (CTSP) find common use in light steel structures and solar panel brackets, yet they are prone to collapse due to local instability and bending failure. To enhance the bending capacity of CTSP, this paper introduces a new composite structure known as gypsum-reinforced cold-formed thin-walled steel tubes (GCTSP), aiming to preserve high stiffness, stability, and lightweight characteristics. The study proceeds in two main phases: Three types of GCTSP (Section sizes of 80mm×40mm, 80m×60mm, 80mm×80mm) undergo four-point bending experiments to determine components

In this study, two types of socket joints manufactured based on a simple design concept and bearing load principle are proposed. The design concept, design method, test program, and FE modelling method for a novel steel dovetail joint without teeth pattern (Interlock type I) and with teeth pattern (Interlock type II) are also discussed. In addition, the tests and numerical analyses of four specimens were conducted to investigate the bearing capacities and failure modes of the new joint systems under axial tensile loads.
