Development of efficient and accurate analysis method for contact problems in mechanical structures

Abstract

A new analysis method for contact problems in mechanical structures is developed in the present research. In the method, linear parameters in contact analysis, such as displacement and force on nodes not on surfaces, are calculated in advance and eliminated in formulation. Since number of unknown parameters is reduced significantly, contact problem is analyzed efficiently and accurately. The effect of developed method is verified by comparing consumer software ANSYS on three-dimensional and three-parts contact analysis. The results by developed method agree with general method calculated by ANSYS and calculation time decrease less than half. Therefore developed method is confirmed to be effective for contact analysis.
