摘要
以某重载机车驱动系统圆柱直齿轮为研究对象,用SolidWorks建立模型并进行分割等模型前处理操作,运用传热学、摩擦学基本理论计算稳态热分析的载荷及边界条件,最后导入ANSYS Workbench进行稳态温度场仿真分析。根据牵引电机的转速工作范围,通过对不同转速下的主动轮稳态本体温度场分析,研究了转速对轮齿温度场分布的影响,为提高齿轮强度和轮齿修形及优化设计提供理论支持。
Taking the cylindrical spur gear of a heavy-duty locomotive drive system as the research object,SolidWorks is used to build the model and perform model preprocessing operations such as segmentation.The basic theories of heat transfer and tribology are used to calculate the load and boundary conditions of steady-state thermal analysis.Finally,ANSYS Workbench is introduced to simulate and analyze the steady-state temperature field.According to the working range of the speed of the traction motor,through the analysis of the steady-state body temperature field of the driving wheel at different speeds,the effect of the speed on the distribution of the temperature field of the gear teeth is studied,which provides theoretical support for improving the strength of the gear,the modification of the gear teeth and the optimal design.
