Analysis And Research Of Motor Tyre Based On Ansys Software

This paper mainly performs the analysis and research on the radial tyre based on the non-linear analysis technology of ANSYS and applied software of ANSYS, using three-dimension volume element, layer element and contacting element, some kinds of three-dimension finite element contact model of radial tyre is built.From the view of the theory of relative movement, the pilot node which is linked with target surface is built, the movement of whole target surface is controlled by the pilot, the pilot node can be regarded as the controller of the target surface, thus, the condition of the force and the moving on the whole target surface are expressed by the pilot node, finally, some kinds of the finite element model about static-contact ,contacting-sliding and model with toe-in and camber are built in order to solve the trouble which is difficult to achieve before , the reference is laid for the dynamic simulation of the radial tyre. Through the analysis of results, the distribution status of contact moulage in diversified conditions and distortion status of the tyre in the different position and distortion trend of tyre in different friction coefficients are accepted , so it poses instructive effects for engineers which engage in structural optimum design and development of radial tyre.On account of the complexity of the tyre structure, so the building of the finite element model about tyre needs sizable workload which canbe not neglected, according to the tyre structural and element characteristic, ansys parametric design language(APDL) is applied for research of the analytic problem so as to relieve the workload of building models and to increase efficiency, so the resembling analysis will be simplified and done easily.
