动车组车下吊挂设备吊装装置的橡胶减振器研究

摘要

Aiming at serious stress of EMU hanging equipment at high-speed operation,vehicles-track coupling dynamics model and body modal basis are used based on damping theory at given frequency range of the vibration isolation system,the characteristics of rubber are combined with its installation space,and the reasonable rubber stiffness and damping parameters are determined.%针对动车组高速运行下车下吊挂设备受力情况严重,这一问题以减振理论为基础,经车辆-轨道耦合动力学模型及车体模态计算,选择了车下吊挂设备自振频率范围,并结合橡胶的特性及其安装空间,确定了合理的橡胶刚度和阻尼参数,为车下吊挂设备吊装装置的橡胶减振器设计提供了依据.
