Abstrakt:
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.
