Dynamic stress analysis on frame of an articulated explosion-proof rubber-tyred vehicle

The dynamic simulation model of the frame of an articulated explosion-proof rubber-tyred vehicle was established by ADMAS.Rectangular-potholed road surface was selected to be simulating pavement according to actual running conditions,and the dynamic simulation and analysis of the vehicle were carried out.After obtaining the maximum force of each component acting on the frame,the dynamic stress of the frame with the maximum force was calculated with finite element software.The dynamic peak stresses of the frame were evaluated,which offered theoretical references for the structural improvement and the optimization design of the frame.
