EFFECT OF ROAD SURFACE ON VIBRATION OF PASSENGER IN BUS VEHICLE

Abstract

This paper presents modeling and simulation model of 6 degrees of freedom
of car - seat - passenger of a 29-seat County vehicle by the vibration in ¼ model.
The excitation forces from three different road surface types are sinusoidal, ramp
and ISO 8608:2016 standard. Newton’s method is used to formulate the
mathematical equations of the model. The simulation method is Matlab Simulink
used. The result of simulation of the three cases all receive the values of vibration
acceleration and motion vertical amplitude at the floor, seat, buttocks, chest,
abdomen and head of the passenger while sitting on the seat to compare with the
value. Mean squared RMS of the accelerometer in the international standard ISO-
2631-1:1998(E). From there, assess the influence of one of the three types of
pavement that has the most impact on passengers.
