城市有轨电车碰撞联合仿真
Research on the City Tram Collision Simulation
摘要
Abstract
In this paper a simulation strategy based on the finite element analyse and multi-body dynamics has been proposed for the collision analyse between a city tram and an oblique obstacle.According to the simulation results the impact angle has been identified as the most determinate factor during the collision between a city tram and an oblique obstacle.With the increased impact angle,the derailment risk of the collided city tram rise significantly.In order to avoid the derailment the maximum impact angle should be reduced to 25°.Besides that,the derailment risk of the collided city tram is also affected by the friction coefficient between wheel and rail.When the friction coefficient decreases due to bad weather,the braking distance of city tram increases,so that the collision accident is more likely to occur.On the other hand,the reduced friction coefficient decreases the wheel-rail forces against the lateral motion of wheel sets.As a result,the collided city tram is more likely to derail.关键词
