高速综合检测列车车体与车下设备耦合振动分析
Coupled vibration analysis between carbody and underframe of high-speed integrated test train
摘要
Abstract
The first test for the speed of 400 km high-speed trains, the establishment of a rigid coupling for the nonlinear system dynamics model on the vehicle. Consider the car under the flexible suspension system vibration in detail. Through simulation and theoretical analysis, the initial state of preparedness of the CIT400 body structure under the car modal parameters and modal parameters suspension device between matches. State of preparedness is given under the car body and the best mode active device parameter matching principle. Determine the device under the car body and suspension parts the best matching parameters. The results show that the method can determine the best car suspension program of high-speed test train under the speed of 400 km according to the dynamic response of the vehicle suspension system.关键词
