摘要/Abstract

摘要：

在考虑套圈结构弹性变形和边界条件的影响下，提出并系统地研究一种以多体动力学方法和有限元方法相结合的角接触球轴承动力学混合计算分析方法。应用ADAMS软件编制了动态接触力和约束方程的用户自定义计算程序，建立了运转过程中考虑钢球和套圈动态接触关系的角接触球轴承柔性多体接触动力学分析模型。在承受不同载荷以及考虑转速、接触角和离心力影响的条件下，分别计算讨论了动态接触力、接触角、振动位移和套圈动态接触应力的变化规律。动力学分析模型较好地模拟了角接触球轴承的柔性多体接触动力学特性，为重载荷、冲击载荷或其他复杂载荷作用下的角接触球轴承的设计、寿命预测和工程应用提供了参考方法。

Abstract:

With the effect of structural elastic deformation of rings and boundary conditions, the paper tried to propose a new dynamics hybrid computing method on angular contact ball bearings based on combining finite element method and dynamics of multibody system. Considering dynamic contact between balls and ring’s races, the new multi-flexible bodies contact dynamics analysis models of angular contact ball bearings were established by ADAMS. The calculation programme was written for dynamic contact force based on penalty method. Considering the effect of different load parameters, rotate speed and centrifugal force, the distributions and rules of dynamic contact force, contact angle, vibration displacements, dynamic contact stress and strain were discussed. The new dynamic analysis model and simulation results have significances in guiding the design, analysis and application of angular ball bearings with the purpose of vibration and fatigue life with heavy loads, impact loads or complex loads.

Key words:
