Research on the Chassis of Aircraft Recovery Trailer Based on ANSYS

Abstract

The traditional method of finite element that fixing constraint between suspension and chassis for the damaged aircraft recovery trailer chassis usually ignored the buffer function of suspension leading to too much stress, So aiming at that problem The constraint of trailer is fixed by the method of balance frame system. Based on FE-software ANSYS the FE module of trailer chassis and balance frame system is set up and their node is coupled by the force analysis of aircraft with half of fuel in damaged. It's result that the maximum stress is less than permissible stress.The result show that the method of balance frame system is more practical by computer simulation.
