本文在分析转向架载荷传递及其力学模型基础上,研究一种在途重载铁路车辆超偏载状态实时检测的方法,并设计了一套基于该方法的车载式超偏载状态监控系统。最后,文章探讨了EMD(Empirical Mode Decomposition)方法用于特征信号的提取,通过仿真信号进行分析,证明了在车辆运行状态下,EMD对检测信号分析的可行性。 Based on the analysis of the bogie load transfer and its mechanical model, a method for real-time detection of overloading and overloading of heavy haul railway vehicles in transit is studied and a set of monitoring system for overloading and overloading of vehicle based on this method is designed. Finally, EMD (Empirical Mode Decomposition) method is used to extract the feature signal, and the simulation signal is used to analyze the feasibility of the EMD signal analysis in the running state of the vehicle.
