Dynamic Analysis of the Gear Transmission System of High-speed Trains Based on IHBM

为了掌握高速列车齿轮传动系统在驱动端、负载端转矩激励下的动力学特性,建立了高速列车齿轮传动系统纯扭转振动模型;利用增量谐波平衡法(Incremental Harmonic Balance Method,IHBM)得到了系统在驱动端、负载端转矩激励下的解析解,与系统数值解进行对比,验证了IHBM的合理性;通过绘制系统的频响曲线,分析了驱动端、负载端转矩激励中主要参数的变化对系统动力学特性的影响。结果表明,在驱动端、负载端转矩激励的参数变化下,系统中出现了多个高阶超谐共振区、幅值跳跃、1个甚至多个多值解区域等非线性特征。研究结果对于深入分析在驱动端、负载端转矩激励下的高速列车齿轮传动系统的动力学特性具有独特的参考价值。

In order to grasp the dynamic characteristics of the gear transmission system of high-speed trains under the torque excitation of the driving end and the load end,the pure torsional vibration model of the gear transmission system of high-speed trains is established.The analytical solution of the system under the torque excitation of the driving end and the load end is obtained by using the incremental harmonic balance method(IHBM).The rationality of IHBM is verified by comparing with the numerical solution of the system.By drawing the frequency response curve of the system,the influence of the change of the main parameters in the torque excitation of the driving end and the load end on the dynamic characteristics of the system is analyzed.The results show that there are several high-order super harmonic resonance regions,amplitude jumps,one or more multi-valued solution regions and other nonlinear characteristics in the system under the parameter changes of the driving end and the load end torque excitation.The research results have a unique reference value for in-depth analysis of the dynamic characteristics of the gear transmission system of high-speed trains under the torque excitation of the driving end and the load end.
