Optimization Analysis of Chassis Rear Axle Segment Structure in a Coach Underframe Based on HyperMesh
The authors use HyperMesh software to do the strength analysis and structure optimization for a coach framework with the finite element method.In the structure optimization,they first determine the spe-cific improvement area,then research the influence of different structure schemes of rear axle segment on the coach framework strength,and finally determine an optimal structure,which can not only ensure the coach framework strength,but also meet the function requirements.
