摘要

Tramcar is important railway conveying equipment in acclivitous shaft of mine. During conveying, tramcar and track often vibrate because there are some excitements. Intensive vibration often causes run-away tramcar accident, and causes deformation of tramcar body. The present paper develops a coupling vibration model to analyze the vibration characteristics of tramcar and track when tramcar goes through a step between two tracks. In the present paper, tramcar is regarded as two degrees of freedom spring-mass-damper model. And, the Bernoulli-Euler beam locating on continuous and elastic ballast is used as the mechanical model of track. The tramcar and the track couple each other by the nonlinear contact force existing between the wheels of the tramcar and the track. The vertical vibration of the tramcar body and the transversal vibration of the track are simulated dynamically. The coupling vibration characteristics of the tramcar and the track are obtained based on this simulation. The wheel/track impaction force and the vibration amplitude of the tramcar body are controlled if the velocity of the tramcar is 1.5m/s.
