摘　　要：鉴于经典Hertz接触理论的局限性,基于有限元方法,应用ANSYS建立十字轴万向节传动轴滚针轴承的非线性接触模型,求解了滚针轴承的接触穿透值及接触应力。结果表明:应用ANSYS计算分析滚针轴承的接触问题是可行的,其结果较符合滚针轴承受力变形后的实际情况。求得的滚针轴承的接触穿透值及接触应力的分布情况为滚针轴承设计及轴承失效形式分析提供了一定的理论依据。Because of the limitation of classical contact theory, this paper builds nonlinear contact model and calculates contact penetration and stress of needle beating based on the finite element method. The simulation results show that, it＇s feasible using ANSYS to analyses contact problem of needle bearing and the solution accords with the fact. The obtained distribution of needle bearing＇s contact penetration and contact stress provide theoretical basis for design and failure form analysis of needle bearing.
