Dynamics Analysis of Railway Piggyback Transportation Vehicle in Piggyback Transportation System

Based on the research on the dynamic test results of the piggyback transportation system, this paper analyzes the influence of vehicle vibration acceleration on the running stability of the vehicle during the operation of the railway piggyback transportation vehicle. The results show that the increase of vehicle speed from 90km/h to 130km/h will increase the longitudinal vibration acceleration of the railway piggyback transportation, and the value will increase from 0.64g to 0.98g. The lateral acceleration has little effect and the values are below 0.4g, but at a running speed of 130km/h, the smoothness effect caused by the vibration acceleration is above the safety level of two or more.
