An Identification Method for Joint Parameters Based on Finite Element

Abstract:

Aiming to solve the problem of joint surface stiffiness identification,this paper presents a finite element identification method. The method based on finite element simulation and the curve fitting principles, fitting out a curve that closed to simulation results. It can identify the joint surface stifiness effectively and rapidly based on curve fitting of simulation data in sensitivity area. This method avoid the transfer function matrix difficult to test and reverse solve problem. Comparing the results of the proposed method with the substructure synthesis method, it is shown that finite element identification method is effective.
