The Finite Element Model

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.

From the designer’s point of view, the static precise finite element model of the single ball-raceway, the overall and the unit slice of the rolling linear guide (RLG) are established based on the limited data obtained. According to the contact characteristics of a single ball-raceway, Hertz theory and finite element method (FEM) are used to determine the maximum contact stress and deformation of RLG under a specific preload value. The specific modeling process of the overall and unit slice finite element model of the RLG is described in detail as well. The comparative analysis results indicate that the unit slice finite element model can take place of the overall finite element model at the static level. On the basis of previous research, the mapping laws between external load, preload value, curvature ratio, the carriage’s wall thickness, the guide’s width, and static mechanical properties of RLG are studied. The combined application of these precise finite element models can solve the problems of large calculation and low efficiency in statics of RLG. Meanwhile, it also provides a new way to achieve high-efficiency and high-rigidity design of RLG from the source.

The three-dimensional solid model and finite element model of an inertial navigation platform, is established by using ANSYS software. A modal analysis has been carried out. The former 6 ordered nature frequency and modal shape have been obtained and kept away from the frequency of Laser Gyro. The finite element model of the system vibration is established and is analysed for harmonic response. The calculation data show that vibration amplitude is very small and has no influence for the Laser Gyro working. The theory modal data is the same as the modal test results, so it manifests the accuracy and effectiveness in the modeling and analysis.

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.

Torsional Analysis

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.
