| Abstract: | A bus frame FEM model is built up with shell and beam elements,which is proved to be accurate by static electrometric tests.This article proposes a new idea that by calculating the limited combined condition to test the stiffness and strength of the bus body frame.By using this method,the aim of verifying the stiffness and strength of the bus body frame meet the use requirements is achieved.In addition,this method provides new inspirations for the choices of condi tions in bus body frame finite element analysis. |
