中文摘要：

根据关节轴承相关的热传导理论,建立了基于ABAQUS仿真软件的动态热力耦合模型,分析了编织衬垫关节轴承温度、应力、变形的分布规律及摩擦热对轴承力学性能和结构尺寸的影响。运用自制的关节轴承试验机对轴承温度进行实时测量,得到热平衡状态时关节轴承内圈温度场的分布,并与ABAQUS热力耦合模型中关节轴承试验测点所对应的温度场分布进行对比。结果表明：相较于无摩擦热时,有摩擦热时内圈和衬垫的变形量变小;在接触区域衬垫变形呈现波动分布,与内圈的接触面积变大。适当的摩擦温度可以缓解编织衬垫关节轴承的应力变化,改善关节轴承的力学性能,延长使用寿命。试验与仿真结果的一致性验证了仿真模型的准确性。

英文摘要：

According to the related heat conduction theory,the dynamic thermal mechanical coupling model for spherical plain bearings with woven liner is established based on ABAQUS. The distribution rules of temperature,stress and deformation and the influence of the friction heat on the mechanical properties and the structure size of the bearings are analyzed. The temperature is measured in real time by self-made spherical plain bearing tester,and then the tested result and simulation result are compared for distribution of temperature field of the inner ring of the spherical plain bearing at the thermal equilibrium state. The results show that the deformation of inner and liner are both smaller under the effect of friction heat than those without friction heat,the liner deformation presents wave distribution in the contact region,and the contact area with inner ring becomes larger. The appropriate friction temperature can alleviate the stress change of the spherical plain bearings,improving the mechanical properties of the spherical plain bearings and prolonging the service life. The consistency of the results of the experiment and the simulation verify the accuracy of the simulation model.
