Finite Element Analysis Based on Structural Parametric Design and Its Application

For many series of products which has similar structure, it is easy to adjust the geometric model of products by using structure parametric design method. 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 simslar model and analysis of series of products. Further more, the efficiency is improved and the time for product design will be shortened greatly. By using the ANSYS Parametric Design Language(APDL), the FEA process including creating FEA model and analysis steps is discussed. A practical parametric FEA model is established and stress analys is done by using our method. The results show that this method is very efficient in FEA of a structure.
