RESEARCH ON THE EFFECT OF SPEED TO VIBRATIONS OF SAMCO FELIX COACH

Abstract

This paper presents the results of studying the effect of speed on the vibration
of Samco Felix coach on the random road surface according to ISO 8608:2016. The
method of separating the structure of the multi-body system and the Newton -
Euler equations is used to build the model and the system of dynamic equations
of the vehicle. The results of the vibration survey using Mathlab - Simulink
software show that when the vehicle moves at a speed of less than 75km/h on
type D roads, or less than 90km/h on type C roads, or less than 100km/h on type B
road, the evaluation parameters of vibration such as smoothness of movement
and safety of dynamics all meet the requirements according to TCVN 6964 - ISO
2631 and VDI - 2057 standards.
