By using the ANSYS Parametric Analysis, the FEA process including creating FEA model and analysis steps is discussed. A practical parametric FEA model is established and stress analysis is done by using our method. The results show that this method is very efficient in FEA of a structure. Based on the idea of the structure parametric design method in Finite Element Analysis （FEA）, a method for building a parametric FEA Model by using parametric design language is provided. By using this method, the FEA model can be easily create by adjusting several geometric parameters and the process of FEA is automatically executed. The remarkable effect of this method is that it is more convenient for repeated FEA for a similar model and analysis of series of products. Furthermore, the efficiency is improved and the time for product design will be shortened greatly.
