BOUNDARY ELEMENT-COMPLIANCE MATRIX METHOD FOR 3D ELASTIC FRICTIONAL CONTACT ANALYSIS

IntroductionContact with friction is a common phe-nomenon in engineering,such as gear drive andfriction drive etc.It is difficulty to analyze contactproblems because of friction,existing very com-plex nonlinear become of a large number of unilat-eral friction contact surfaces,on which the contactfluctuates. Thus the analysis of frictional contactbehavior is regarded as one of the most challengeproblem in solid mechanics field.Many experts devoted in studying the friction-al contact problem1～…

BOUNDARY ELEMENT-COMPLIANCE MATRIX METHOD FOR 3D ELASTIC FRICTIONAL CONTACT ANALYSIS

Boundary element compliance matrix (BEM) method to deal with 3D elastic frictional contact problem was presented, and its calculation method and convergence criteria were discussed. It has the advantages of both boundary element method and compliance matrix methods: small number of inputting data, simple and convenient model, precise solution, short calculating time and requirements for a small quantity of computer memory. In comparison to the other BEM with friction problems, we obtain more precise solution and less iteration times. The effect of friction coefficient on contact area. contace state, and relative displacement, normal and tangential stress was analyzed by two examples. And because of the quickness of calculation of program and efficient method, we visualize the result in virtual reality (VR) environment. We grant the real time of VR and provide more immersion to users who ware the VR device.
