STUDY MODEL AND ANALYSIS OSCILLATION OF SLEEPER COACH IS MANUFACTURED, OPERATED AND EXPLOITED IN VIETNAM IN FREQUENCY DOMAIN

Abstract

ABSTRACT
These are many factors effect on oscillation of sleeper coach. One of the most
main effect is road profile. Common road profile is represented by sine profiles. In
frequency domain different sine profiles are written by two parameters is
amplitude and frequency. The effect of different road profiles on vehicle is
expressed by transfer function matric between road profile and displacement of
sprung mass. Study model in article is full car vibrating model. The equations of
motion for the full car vibration model of sleeper coach includes seven equations
correspondingly seven freedom degrees. The equation of motion is written by
matric form. Function transfer matric will be calculated by numerical method and
use the Matlab software.
