摘要:对经典接触计算方法与有限元接触问题计算方法进行了对比研究。经典的计算方法结果精确,计算简单,但是应用的范围有限;有限元法相对复杂,但是应用的范围很广泛。利用HYPERWORKS平台,对经典的赫兹接触实例进行了隐式非线性准静态分析。得到的数值解与赫兹理论的解析解作对比,发现RADIOSS求解器能够较好地模拟接触问题,验证了有限元法计算接触问题的结果是完全正确的。

Abstract:This paper is based on the research of classical contact analysis and finite element method contact analysis. The results calculated by classical method are more precise than FEM, and classical method is more convenient than FEM, but FEM contact analysis is widely used, because it can be applied to different kinds of contact problems. Utilize the platform of hyperworks, the classical implicit nonlinear quasi-static analysis is proceeded for the example of Hertzian contact. Compared the numerical solution with the analytical solution of the Hertz theory, comes to the conclusion that the radioss solver can better simulate the contact problem, the results testify that it is feasible to do contact analysis by FEM contact analysis.
Key words:RADIOSS;contact analysis;Hertz theory
