摘要:
传动齿轮箱作为高速动车组走行系统的核心部件，直接决定列车的运行速度和运行状况，对列车的行车安全起着至关重要的作用。提出了一种基于Lasso回归的动车组齿轮箱性能检测方法，通过分析动车组齿轮箱实际运行时的性能指标与其期望值的偏离情况，检测动车组齿轮箱的异常状态，进而识别动车组齿轮箱的早期故障。实例验证了基于Lasso回归的动车组齿轮箱性能检测方法的有效性和可行性。
Abstracts:
As the core component of high-speed EMU running system, driving gearbox directly determines the running speed and operation status of the train, which plays an important role in the operation safety. A performance examination method for high-speed EMU gearbox based on the Lasso (Least Absolute Shrinkage and Selection Operator) regression was proposed. By analyzing the deviation between actual values and expected values of the performance index for high-speed EMU gearbox, the error state was detected and the initial failure was identified. Furthermore, simulation example results show the effectiveness and feasibility for Lasso regression to be applied to detect the performance of gearbox.
