Open full text 2 citations

Abstract

Using the multi-body system dynamic method, a steering mechanism simulation model is built and dynamics simulation analysis is studied.We have built a flexible tie-rod model and attained the natural modes using the finite element software of ANSYS.In this paper, a rigid-flexible coupling steering mechanism model is built using the software of ADAMS and ANSYS with the flexible tie-rod model.The torques of the trapezoidal steering arm during a bumping are analyzed.The dynamics characteristics of the multi-body rigid model and the rigid-flexible coupling model are compared.The accurate simulation results of the rigid-flexible coupling model were verified by simulation test.
