摘要：The paper presents an analytical approach to the problem of Vibration Induced SpeedDeviation of a Carriage on Towing Tank. Starting from early studies based on a simply supported beaminteracting with a lumped mass moving at constant speed, in recent years researchers have improved themodels of both the rail and the vehicle. On this basis, the rail is analyzed by FEM to gain rail deflection insome rail chair distances. The analytical method shows that deviation of rail in static and dynamicdeflection has little effect in vibration of rail and it can be neglected
