【摘要】：针对角接触球轴承结构进行静态接触特性分析,研究了联合载荷对结构接触特性的影响机制。依据赫兹接触理论,设定了求解接触应力与接触角的计算方法;利用ANSYS软件建立了角接触球轴承结构模型,并提出了加载方案及约束的设定方法;将仿真结果与赫兹理论结果进行对比,验证了本文建模方法、加载方式的正确性。最后,利用本文模型探讨了联合载荷下的接触应力、接触应变、接触角、接触椭圆的变化规律及影响,为复杂加载工况下轴承的设计及应用提供工程分析参考。
[Abstract]:The static contact characteristics of angular contact ball bearings are analyzed and the influence mechanism of combined loads on contact characteristics is studied. According to Hertz contact theory, the calculation method of contact stress and contact angle is set up, and the structure model of angular contact ball bearing is established by using ANSYS software, and the loading scheme and constraint setting method are put forward. The simulation results are compared with the results of Hertz theory to verify the correctness of the modeling method and loading method. Finally, by using this model, the changes of contact stress, contact strain, contact angle and contact ellipse under combined load are discussed, which provides an engineering analysis reference for the design and application of bearings under complex loading conditions.
