| Abstract: | A new method solving structrual dynamic stress in finit element is presented in this paper. Stuctural dynamic stress can be obtained conveniently, which use solution of finite element and calculation of finite difference on modal function. Finally, we use the new method to analyze and calculate the example. The results of calculation is high compared with finite element,and its calculation volocity is fast compared with dynamic finite element. |
