摘要

A simplified rigid-flexible coupling dynamical model of the rail operating vehicle,including bogie frame and car body,was built.The car body is modeled as a flexible uniform Euler beam.The dynamical response of the vehicle under the irregularity dynamic action between wheel and rail was numerically calculated and analyzed by the fast stability algorithms.Influences of the suspension on vibration and stability of the vehicle are analyzed.The results have a certain reference value on the dynamic design of multi-functional track operating vehicle.
