ANALYSIS OF VIBRATION EXPERIENCED BY PASSENGERS AND THEIR SEATS IN A BUS VEHICLE

Abstract

This paper presents an analysis of the vibration experienced by passengers on
a 29-seat bus, using the finite element method and Ansys Workbench software
for simulation. The 3-D model was created to simulate real-life conditions, with a
sinuous road surface that causes direct forces on the four wheels, leading to
vehicle vibration. The force model was analyzed from the floor of the vehicle,
specifically in one seating position, to assess the level of vibration that the seat
and occupants experience. This analysis can be extended to other seating
positions on the vehicle. The vibration parameter of human comfort level was
evaluated based on frequency, as per the international standard ISO 2631-1. The
research results can be used as a reference for designing seat cushions and seating
positions in buses, to improve the comfort level of passengers.
