动车组车下吊挂设备吊装装置的橡胶减振器研究

Study on Rubber Isolator of Hoisting Device for Hanging EMU Equipment

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.

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 vibra- tion isolation system, the characteristics of rubber are combined with its installation space, and the reasonable rubber stiffness and damning nnrameters are deterrmined.
