| Abstract: | Accuracy of surface modeling is important in the simulation of mechanical systems.In order to effectively solve the surface problem in finite element modeling,the surface parameters were identified through experiments and then were used for finite element modeling in engineering applications.Hertz theory and modal analysis method were used to identify the surface parameters of the rolling guide-way,and the accuracy of finite element modeling was verified by simulation analysis. |
