In this paper, an elastic deformation of the axial foil hydrodynamic thrust bearing used in 100KW gas turbine generator is studied. The finite element model of the foil hydrodynamic thrust bearing was established using Solidworks and ANSYS. The foil hydrodynamic thrust bearing which considered foil deformation was analyzed and calculated based on the results of the approximate calculation. The FEA model considered the interaction of plane foil deformation and wave foil. The wave foil was not hypothesized as the linear distributed spring when set up the finite element model. The ANSYS results have demonstrated that the deformation of foil bearing designed based on the result of numerical calculation can meet the requirement of minimal film thickness of bearing lubricant layer.

Over the past years, numerical investigations have gained more attention and success in analysing the overall performance of hybrid FRP-concrete structures in civil engineering applications. In this study, a hybrid FRP-geopolymer concrete beam, which consists of high-strength geopolymer concrete filled into a rectangular hollow section pultruded GFRP profile, has been investigated numerically using the commercial software ABAQUS. A non-linear finite element model has been developed to simulate the flexural behavior of this hybrid beam under four-point static loading. Different material models were employed to describe the materials used for the hybrid beam members. The numerical results including the flexural capacity and load deflection curves are compared and verified with published experimental data from literature. The determination of dilation angle of geopolymer concrete and the effect of mesh dimensions are also compared and reported in this study. A reasonable agreement between experimental data and the numerical result is obtained, which indicates the finite element model developed in this numerical investigation is able to predict the non-linear behavior of this hybrid beam.

Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.

Abstract A three-dimensional (3D) beam finite element model was developed to investigate the torsional stiffness of a twisted steel-reinforced cord-rubber belt structure. The present 3D beam element takes into account the coupled extension, bending, and twisting deformations characteristic of the complex behavior of cord-rubber composite structures. The extension-twisting coupling due to the twisted nature of the cords was also considered in the finite element model. The results of torsional stiffness obtained from the finite element analysis for twisted cords and the two-ply steel cord-rubber belt structure are compared to the experimental data and other alternate solutions available in the literature. The effects of cord orientation, anisotropy, and rubber core surrounding the twisted cords on the torsional stiffness properties are presented and discussed.
