摘　　要：以某电动轨道打磨作业车齿轮箱为研究对象,通过对齿轮传动系统进行理论分析,采用解析法计算齿轮系统的刚度和啮合冲击激励,以简谐函数模拟误差激励并合成齿轮内部激励,建立了包含齿轮副、轴、轴承以及箱体在内的有限元分析模型,并用弹簧单元模拟轴承的支承作用和轮齿啮合,应用完全法求解齿轮箱振动响应;而后,搭建电传动车轴齿轮箱振动测试试验台,开展了振动响应测试。结果表明,电动轨道打磨车车轴齿轮箱振动预估结果与试验吻合较为良好,验证了分析模型的合理性;研究结果为后续齿轮箱的开发与交付提供了数据支持。Taking the gearbox of an electric orbital grinding work vehicle as the research object,the theoretical analysis of the gear transmission system was carried out,the analytical method was used to calculate the stiffness and meshing impact excitation of the gear system,and the error excitation was simulated with simple harmonic function and synthesized with the internal excitation of the gear.A finite element analysis model including the gear pair,shaft,bearing and box was established,the spring unit was used to simulate the bearing support and gear tooth meshing,and the complete method was applied to solve the vibration response of the gearbox.After that,an electric drive axle gearbox vibration test bench was built to carry out the vibration response test.The research results show that the vibration prediction results of the axle gearbox of the electric rail grinding car are in good agreement with the test,which verifies the rationality of the analytical model.This study provides data support for the subsequent development and delivery of the gearbox.
