The Application Of ADAMS/Rail On Dynamic Simulation Analysis Of The High-speed Train-track(Turnout) System

With the increment of the running speed, the dynamic problems of the train-track(turnout)become more and more evident.This paper focus on the admissible limit speed meeting the requirement of safety and comfortableness, the plane and vertical section design parameters of railway line which affect the running safety and comfortableness and the dynamic problems of train-turnout system.Hoping to provide a reference for the maintenance and repair of high-speed railway. The main work done in this paper is as follows:(1) A train-track time-variable system space vibration analysis model based on ADAMS/Rail software is established and validated.(2) Making a dynamic simulation analysis of the plane and vertical section design parameters of a high-speed railway in China by using the established model and compares the result with the existing dynamic standards, thus to assess whether these parameters meet the requirement of safety and comfortableness.(3) Making a dynamic simulation analysis by using the established mode of train-turnout and compares the result with the existing dynamic standards, thus to assess whether these parameters meet the requirement of safety and comfortableness.(4) Calculating the admissible limit speed meeting the requirement comfortableness basing on the limit speed meeting the requirement safety, providing a reference for the maintenance and repair of high-speed railway.
