摘要/Abstract

摘要： 为了获得最优高速列车牵引电机冷却风机双层悬挂参数，对轮轨和设备激励共同作用下的风机悬挂参数选择进行研究。建立车辆-设备动力学模型，并对系统振动响应进行积分求解，探讨刚、弹性悬挂，单、双层悬挂风机的振动特性。根据风机、框架悬挂参数对系统振动特性的影响筛选出最优悬挂参数取值范围，基于风机、框架悬挂参数匹配关系确定最佳悬挂频率比。研究结果表明，风机系统悬挂参数对车辆舒适度影响较小，但会影响风机系统振动，风机采用双层弹性悬挂能显著降低自身振动，当框架悬挂频率比取0.7～0.9，风机悬挂频率比取1.8～2.0时风机系统能获得较好振动水平。根据悬挂参数匹配关系，最终确定风机、框架最优悬挂频率比分别为1.8、0.9。

Abstract: In order to obtain the optimal double-layer suspension parameters of traction motor cooling fan for high-speed train, the selection of the fan suspension parameters is studied under the combination of wheel rail and equipment excitation. The dynamic model of vehicle and equipment is established and the system vibration response has been solved by integral method. According to the influence of fan and frame suspension parameters on the vibration characteristics of the system, the value range of the optimal suspension parameters are selected, and the optimal suspension frequency ratio is determined based on the matching relationship between fan and frame suspension parameters. The results show that the suspension parameters of the fan system have little influence on the comfort of the vehicle, but can affect the vibration of the fan system. The double-layer elastic suspension can significantly reduce the vibration of the fan system itself. When the frame suspension frequency ratio is set at 0.7-0.9 and the fan suspension frequency ratio is set at 1.8-2, the fan system can achieve a better vibration level. According to the matching relation of hanging parameters, the optimal hanging frequency ratio of fan and frame is determined to be 1.8 and 0.9 respectively.
