Currently, many passenger buses are equipped with air suspension systems. These systems are affected by various factors, such as vehicle speed, load, and road surface quality, which can cause vibrations. Among these factors, road profile conditions have a significant impact on the ride comfort and dynamic load of the vehicle. This paper presents a spatial vibration model that evaluates the vibration of passenger buses equipped with air suspension systems when traveling on random roads, following the ISO 8608:2016 standards. The evaluation criteria include ride comfort, dynamic load, driving safety, and suspension space. The results of this study can serve as a basis for designing control systems that improve ride comfort and reduce the impact of dynamic load on the road.
