Structural Simulation Analysis of Frame and Suspension System of Super-heavy Load Carrier Platform
This study focuses on the structural performance analysis of the frame and suspension system,and uses CATIA to construct the three-dimensional structural of the frame and suspension system of a certain type of super-heavy-duty transport platform,and constructs the finite element model of the system structure.Based on the future practical application requirements of this type of vehicle,seven types of typical unfavorable working conditions,such as impact,braking and torsion,which may be experienced during complex operation,are selected to carry out performance simulation analysis of the system structure of the vehicle,to obtain the stress situation of each component under a variety of complex operating conditions,and to explore the risk of structural failure.The simulation results show that the maximum stress of some parts of the frame under torsion exceeds the yield limit of the material,and it is mostly found in the welding place between the cross beam and other parts.In view of this kind of problems,corresponding improvement suggestions are put forward,and a double-layer rigid-flexible coupling composite high load-bearing frame and heavy-duty suspension system is constructed,which has good load-bearing capacity and is successfully applied to the over 100 tonne emergency transport vehicle.
