摘要/Abstract

摘要： 联轴器是高速列车传动系统的关键环节，必须要求其在传递扭矩的同时兼具位移补偿特性，以保证列车运行的稳定性和可靠性。引入弹性体实现偏载时的位移补偿和附加径向力削减，提出一种可替代或部分替代高速列车转向架系统内传动装置的新型永磁-高弹复合联轴器，并采用满布磁钢提升结构的紧凑型和传递转矩。基于等效面电流法和弹性力学理论，推导永磁-高弹复合联轴器的传递转矩和径向力解析模型，与试验结果相比，相对误差分别优于3.98%和13.27%，可以满足工程应用前期快速的预设计指导。同时，与传统筒式永磁联轴器对比，所提永磁-高弹复合联轴器的径向力减小了73.9%，表明其具有抗偏载和自对中特性。最后，对磁组阵列和弹性体关键参数进行了影响特性分析，并相对传统弹性联轴器进行了模拟列车载荷激振试验，所提永磁-高弹复合联轴器振级落差优于2.3 dB，减振效果较好，表明其在高速列车传动系统内应用具有重要参考价值和前景。

Abstract: Coupling is the key link of high-speed train transmission system, and it must be required to have displacement compensation characteristics while transmitting torque to ensure the stability and reliability of train operation. Elastomer is introduced to realize displacement compensation and additional radial force reduction under eccentric load, and a new type of permanent magnet-elastomer composite coupling is proposed, which can replace or partially replace the transmission device in the bogie system of high-speed trains, and the compactness and torque transmission of the structure are improved by using magnetic steel. Based on the equivalent surface current method and the theory of elasticity, the analytical models of transmission torque and radial force of permanent magnet-elastomer composite coupling are derived. Compared with the experimental results, the relative errors are better than 3.98% and 13.27% respectively, which can meet the rapid pre-design guidance in the early stage of engineering application. At the same time, compared with the traditional cylindrical permanent magnet coupling, the radial force of the proposed permanent magnet-elastomer composite coupling is reduced by 73.9%, which shows that it has the characteristics of anti-eccentric load and self-centering. Finally, the influence characteristics of key parameters of magnetic array and elastomer are analyzed, and compared with the traditional elastic coupling, the simulated train load excitation experiment is carried out. The vibration level drop of the proposed permanent magnet-elastomer composite coupling is better than 2.3 dB, and the vibration reduction effect is good, which shows that it has important reference value and prospect in the application of high-speed train transmission system.

Key words: permanent magnet-high elastic composite coupling, equivalent surface current, transfer torque, anti-unbalanced load, vibration reduction
