Evaluation of travel comfort of passengers – relationship between vehicle and environment

Abstract

The aim of this paper is to present in more detail a part of the passengers’ travel comfort evaluation method in a rolling stocks design. This paper deals only with an interaction between a VEHICLE and an ENVIRONMENT. Introduced part of the method is focused on a mathematical model design of acting environmental factors on the vehicle and their random behaviour. The selected environmental factors are noise, vibrations, light and heat. Definition of sources of the selected factors are designed, their manners of a propagation in a surrounding (energetic path tracing) and statistical complex evaluation of final intensity of the selected factors in a random critical point of the vehicle interior as well. The mathematical model design is a simulation of the vehicles interior, which is possible to parametrically impact by geometrical and material indexes of the vehicle design.
