摘　　要：以CRH2动车组的动力转向架的轴箱轴承(密封双列圆锥滚子轴承)为研究对象,利用温度场和热应力场的耦合关系,对该轴承建立了温度场和热应力分布的数值模型,再通过Matlab软件对建立的模型进行仿真分析和验证。结果表明:所采用的分析方法是合理、可行的,为后续的高速机车转向架传动装置中轴承的设计时的动态分析提供了一定的指导作用。Taking the bearing of power bogie of CRH2 as the research object, based on the coupling relations of temperature field and thermal stress,the numerical model about the temperature field and the thermal stress of double row conical rolling bearing in train bogie of CRH2 is established;the model is solved with numerical analysis,and is simulated by MATLAB software.The results show that the method for analyzing thermal stress is feasible,which is able to preferably simulate the distribution of temperature field and thermal stress of rolling bearings,providing a guide for the design and optimization of rolling bearings,at the same time the method given is available for the engineering application.
