Vibration of the bogie and car body becomes remarkable with train acceleration, and its effect on aspects, such as safety, riding comfort, rails or ground facilities are experienced. Railway vehicle vibration is a problem of importance in terms of safety and riding comfort requiring detailed analysis. The vibration of a railway vehicle is mainly caused by wheels and bogies running on a rail and transmitted to the car body. Of great concern is danger of derailment and riding comfort. In this paper, we focus on the natural vibration of the bogie during acceleration from low speed to high speed and verify the details of the vibration using roller rig model equipment. Comparison and analysis of experiment results and dynamic analysis software of vehicle motion is offered, with attention to vibration of rail wheelset due to mass unbalance and corresponding roller rig model. |
