Effect of floating bridge motion on vehicle ride comfort and road grip
Paper in proceedings, 2019

The aim of this paper is to investigate the influence of floating bridge
motion on bus driver’s ride comfort and road grip for the straight concept
solution across Bjørnafjorden. For this investigation 3 degrees of freedom
(DOF) bus model is defined for numerical simulation. Bus model has been
excited by vertical motion of the bridge for four different bus speeds. Ride
comfort has been assessed according to method and criteria proposed by
International ISO 2631/1997 standard. For road grip assessing Dynamic Load
Coefficient (DLC) has been used. It has been concluded that on floating bridge
‘little uncomfortable’ ISO 2631 criteria is reached at lower bus speed
comparing to stationary ground road. Higher values of DLC for the case of
floating bridge points out higher variation in vertical tyre forces (worse road
grip). For bus speed at 90km/h, DLC for floating bridge is approximately 0.08
which is 7% higher value comparing it to the case of stationary road.
