Sensitivity Analysis of Ride Behaviour of Indian Railway Rajdhani Coach using Lagrangian Dynamics
Main Article Content
Abstract
In this paper, the ride analysis of Rajdhani coach is undertaken using 37 degrees of freedom vertical-lateral coupled vehicle-track model that is formulated using Lagrangian dynamics. The vehicle is considered to be moving along a straight track at a constant speed of 130 kmph. The simulated results of ride behaviour are compared with the experimental data. A sensitivity analysis is carried out in order to investigate the influence of mass and moment of inertia of car body, suspension stiffness, damping coefficient and wheel base on the ride behaviour.
