| Abstract: | Based on the finite element model of cylinder bracket of the original design for heavy truck, according to national standards, three simulation conditions were carried out. By comparison between simulation results and test results, the accuracy of FE mode was verified. Based on the analysis, considering the technology and lightweight, the frame structure was improved, and the resul was verifyied by test., the arts and crafts and lightweight were improved and the goal was reached. |
