Accorrding to the quick development of computer technology,FEA is made extensive application in engineering. ANSYSA is a powerful engineering software, which solve the problems of structure with the finite element method,and regard the whole structure as the unit of many intterrelate substructure,presumes an answer for each element,then deduces the qualification of the whole,and ulimately get the entire answer for the whole. Because the software of ANSYS has the characteristics such as model building simply,fast and conveniently,it becomes the representative of large universal finite element procedure.In terms of composing and function,ANSYS is really an efficient tool in engineering and it plays an important role in static and dynamics analyse.
