Abstract
Vibrations of bus is affected by operating conditions such as velocity and road surface. During the motion, the vibration affects the road, vehicle and driver. Ride comfort is used to evaluate the effect of vibrations on driver through the root mean square acceleration (arms). This research paper determined the limit velocity of bus used the air suspension according to the ride comfort based on surveying the full model. Research results show that ride comfort is only achieved in operating conditions with the velocity does not exceed 55.4 km/h on type A of random road or not exceed 13.7 km/h on type B; when the velocity exceed 44 km/h on type D, this causes extremely uncomfortable feeling for the driver.
