A Review on Dynamic Analysis of Rail Vehicle Coach
TLDR
This paper is an attempt to cover various modelling and simulation methods of the railway bogie and coach adopted by various researchers to understand the dynamic behaviour of the railways coach.Abstract:
Railway vehicle is one of the rigorously developing passenger and goods carrier in the past few centuries. Dynamic behaviour of the railway coach is a vital aspect in its design and also in terms of passenger safety and ride comfort. Dynamic response includes both deterministic and probabilistic analyses. Modal, harmonic and transient dynamic analysis is part of deterministic analyses, whereas random response using spectrum methods and power spectral density (PSD) is a probabilistic approach. This paper is an attempt to cover various modelling and simulation methods of the railway bogie and coach adopted by various researchers to understand the dynamic behaviour of the railway coach. Further, the research findings of various dynamic parameters obtained theoretically and practically against different inputs like sinusoidal and random inputs to the car body have been discussed. This forms a basis in understanding the development of railway coach design when one is interested in carrying out free and forced vibration analysis on the coach, as well as assists to optimize various design parameters of components like bogie, car body and suspension elements in terms of vehicle dynamics.read more

TL;DR: A comparison indicates that the semi-active controller gives the optimum performance based on frequency and time response analysis for comfort vibration actuation and it has little influence on derailment quotients, offload factors, as a result, it will not endanger the running safety of rail vehicle.

TL;DR: In this paper, a detailed model is developed to investigate the vertical interactions between railway vehicles and tracks, in which the vehicle subsystem is modelled as a multi-body system with 10 DOF running on the track with a constant velocity, and the track substructure as an infinite Euler beam supported on a discrete-continuous elastic foundation consisting of the three layers of rail, sleeper, and ballast.
