指出了对同时作用静载荷和正弦载荷的结构进行动力学有限元分析的实际意义,并根据有限元法理论研究了求解问题的原理、方法,进而在通用有限元软件ANSYS中通过实例具体实现了问题的求解过程.经过研究,该方法还可以用于对同时作用多个不同频率正弦载荷的结构进行动力学分析.本方法的使用,将会拓广有限元法的应用范围.

The practical significance of the finite element analysis of kinetics on the structure of simultaneous effect of static load and sinusoidal load was pointed out.According to the theory of finite element method,the principles and methods for solving the problem were analyzed.Then in the general finite element software of ANSYS,through a concrete example,the problem solving process was achieved.This method can be used in the dynamic analysis on the structures of simultaneous effect of many different frequency sinusoidal load.The usage of this method is bound to broaden the applied scope of finite element method.
