| Abstract: | This paper is focused on the problems existing in forming structural small damage FEM when using ansys structure analysis software. It is started the practical need in the vibrating test of the structural damage, to proclaim the method of forming the small damage vibrating model. The result of numerical simulation is shown that it can be used to judge and evaluate the structure damage. It has some potential application. |
