地铁牵引齿轮箱是车辆转矩传递的关键零部件,其一旦发生故障将直接影响列车的运行安全。因此,结合动力学仿真和振动试验,对地铁齿轮箱的断齿故障振动特性进行了研究。首先,根据地铁齿轮箱各部件间的动力学关联及其约束特征,通过冲击函数法、库仑摩擦模型、轴承建模、箱体柔性体和齿轮系统动力学理论,建立了地铁齿轮箱刚柔耦合断齿故障动力学模型,研究了不同断齿故障类型下齿轮箱的动态响应,分析了工况参数对断齿振动特性的影响。其次,通过振动试验,获得了齿轮箱正常和断齿故障状态下的动态响应,对动力学仿真模型的准确性进行了验证。结果表明,刚柔耦合动力学模型可有效计算齿轮箱不同运行状态的加速度响应,为齿轮箱的断齿故障预测和识别提供诊断依据。
Metro gearbox is a key component for torque transmission in vehicles
and its failure will directly affect the safety of train operation. The vibration characteristics of tooth breakage faults in metro gearbox were studied by combining dynamic simulation and vibration test. Firstly
based on the dynamic relationships and constraint characteristics between various components of metro gearbox
a rigid-flexible coupling dynamic model of metro gearbox with tooth breakage faults was established through the impact function method
Coulomb friction model
bearing modeling
flexible body of the housing and gear system dynamics theory. The dynamic response of the gearbox under different types of tooth breakage faults was studied
and the influence of operating parameters on the vibration characteristics of tooth breakage was analyzed. Then
through vibration test
the dynamic response of metro gearbox under normal state and broken tooth fault was obtained
verifying the accuracy of the dynamic simulation model. The results indicate that the rigid-flexible coupling dynamic model can effectively calculate the acceleration response of gearbox in different operating states
provide diagnostic basis for the prediction and identification of tooth breakage faults in the gearbox.
