Research on Characteristic Response Curve of Complex Cam Model Based on PCA Finite Element

Computer numerical modeling is the first step of virtual simulation, but for many models, numerical modeling process is very complex, the workload is huge, we must adopt corresponding algorithm to optimize modeling process. In this paper we introduce the idea of computer PCA in the finite element modeling process, and establish finite element partial differential equation of PCA, which greatly reduces the complexity of the modeling process. We establish a complex cam model by UG software, and verify the reliability of the model and algorithm. At the end of this paper, we apply the finite element computer PCA analysis method to the evaluate sports resources, and establish a new type of city sports resources weight ratio model for Pan Yang Hu area, and obtain the characteristic response curve. It provides computer technology support for the new city sports resources construction and evaluation process.
