Research on dynamic characteristics of an explosion-proof rubber-tyred vehicle

Wenhua Du

Abstract

To investigate the dynamic characteristics of an explosion-proof tire vehicle,and obtain the dynamic stress and strain distribution,simulation research on its dynamic characteristics was conducted with multi-body dynamics and finite element method.An ADAMS-based model of the vehicle was established and dynamic load curves of all hinge points on the rectangular pit road condition were obtained by multi-body dynamic simulation.Then random excitation peaks of dynamic simulation result were applied to the finite element model established through ANSYS under typical load condition.Both dynamic stress distribution and stress concentration locations of the frame were obtained.The research result can be used to evaluate dynamic stress and strain,also providing certain significance for the vehicle lightweight improved design.
