Abstract

Abstract. This research aims to examine the effect of vertical dynamic load of vehicles and
changes in dimensional barriers on the road surface in its path. Experimentally this fluctuating
load is replaced by a pneumatic force change based on the regulation of air pressure on the
regulator. The deviations generated by the varying load work are measured by placing a
proximity sensor along the spring movement. The amount of vertical load transformation
reaches the road surface is measured by using Load cell. Characteristics of vertical dynamic
vibration occurring due to several dimensional barriers, U (cm) obtained using mathematical
modelling method with 2 DOF suspension system transfer function. The results showed a
condition on the body and wheels of vehicles experienced a brief overshot for 0.14 seconds
with deviation of 0.178 m. From the graph shows that the rate of deviation that occurs is large
enough that Y2d = 1.03 m / s caused by a sudden shock that occurred on the wheels of the
vehicle. This condition does not last long that is only duration t = 0.22 s, because the spring
reaction force and shock absorber can absorb 45% vibration against the sprung and un-sprung
vertical load of the vehicle.
