| Abstract: | In this paper,the FEA model of the pump truck is established by taking plate unit as basic unit.The analysis of static stress is made by using MSC/NASTRAN software,and the experiment is done.The results of calculation are accorded with that of the experiment and are verified by that.The reasons for fatigue crack appearing in early stage are found out.The ways for the reconstruction of structure are presented. |
