Abstract
In order to improve the accuracy of simulation model of complex framework-type equipment support and meet the requirements of high strength and light weight, a static loading test was performed to discover the weak links on the basis of finite element analysis. Then, a structural mechanics model was established to obtain the failure mechanism and an improvement scheme was proposed. Finally, the failure mechanism was obtained to improve the local design. The static loading test results show that the improved equipment support has no obvious plastic deformation and the local design improvement is effective, meeting the requirements of aviation limit overload. Therefore, the design method, combining simulation, experiment and theoretical model, can improve the product strength with little material increment, which can provide an effective way to improve the design of framework-type equipment supports.
