Ride Comfort Evaluation for the Korean Experimental High-speed Train
Ride comfort is one of the most important dynamic performance characteristics of railway vehicles and it is affected by various factors such as vibration, noise, smell, temperature, visual stimuli, humidity and seat design. Evaluating ride comfort is not simple because all these factors must be considered simultaneously. In general, vibration, which originates from vehicle motion, is taken as t...
متن کاملExperimental and Analytical Ride Comfort Evaluation of a Railway Coach
The dynamic performance of a railroad vehicle as related to safety is evaluated in terms of specific performance indices like ride quality. The ride quality is interpreted as the capability of the railroad vehicle suspension to maintain the motion within the range of human comfort and or within the range necessary to ensure that there is no damage to the cargo it carries. The recent trend in dy...
متن کاملA Study to Predict the Development of Wear for the Wheel/interface of a Railway Track
The train transport is often confronted with greatly repeated changes in scope, vehicle travel well-being and transport safety because of the adjustments of wheel and rail profiles. These problems are frustrating and threatening. Thus, there is a requirement for an approach to predicting the wear of wheel/rail to tackle these problems. A new theoretical ground is broken through the build-up a m...
متن کاملDevelopment of a Finite Element Methodology for Flexible Track Models in Railway Dynamics Applications
The dynamic analysis of railway vehicles involves the construction of three independent models: the vehicle model; the track model; and the wheel-rail contact model. In this work, a multibody formulation with Cartesian coordinates is used to describe the kinematic structure of the rigid bodies and joints that constitute the vehicle model. A methodology is also proposed in order to create detail...
متن کاملInfluence of slab length on dynamic characteristics of subway train-steel spring floating slab track-tunnel coupled system
A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditions and train speeds are theoretically...
