| Abstract: | In this paper, Parameter Variable technique is used to establish finite element model for trailer frame of 60 ton heavy transport truck , and 10-Node Tetrahedral Structural Solid elements are used for FEM mesh, which greatly improves building efficiency , revisability and of model than tradition methods. The simplification methods of FEM model and the mechanics analysis methods in various working conditions are introduced. The construction is updated according the result, and the computations are checked. Finally, the reasons of FEM solving mistake are discussed. |
