Abstract

The two most important parameters in driving are comfort and stability. To get the best value from that parameter, then the role of the vehicle suspension system is very important to reduce the vibration due to road waves and keep the wheels sticking above the road. This study studied the effect of suspension type on comfort level and vehicle stability. The type of suspension is related to the value of spring stiffness and its damping value. While the vehicle is modeled in one degree of freedom. The test is carried out with vehicle loading including mass of vehicle and passenger for each type of suspension, ie soft, medium and hard. Vibration analysis is done using Matlab Simulink to get the acceleration response and its deflection response. The vibration response graph shows the comparison of comfort level and vehicle stability on the road profiles modeled in step, impulse, and sinusiodal functions. From the simulation results obtained that Soft and Medium Suspension can handle the vibration very well especially from the level of response speed for a relatively flat road. Meanwhile, Suspension type Hard very good damp vibration for high wavy road.

Abstract

The comfort of the vehicle passenger of the vehicle and its stability are the important variables that are always needed by everyone who uses transportation. In order to achieve this goal, the suspension of the vehicle will play an important role because its function is to isolate passengers from the effects of excitation from outside the vehicle and also to control the wheels attached to the road surface. Therefore in this study, the influence of various types of suspensions on vehicle vibrations is observed in terms of comfort and stability. The type of suspension in this study is related to the level of suspensión stiffness namely the spring and the damper. Vehicle modeling to be applied in a one-wheeled vehicle with two degrees of freedom. The experimental study is conducted by loading of vehicle body weight and passengers to three type of suspension, soft, medium and hard. Vibration responses to be analyzed on the vehicle equation using Matlab to obtain the acceleration response of the displacement and the defelction. This research obtains a vibration response graph for each type of suspension for some kind of road profile.

Abstract

The two most important parameters in vehicle vibration are the level of comfort and stability. To get the best value from that parameter, the vehicle suspension system is very important to reduce vibration due to road waves and keep the wheels attached to the road. This paper studied the effect of the type of suspension on the vibration of a one-wheeled vehicle in terms of comfort and stability. The type of suspension is related to the value of the spring stiffness and the damping. While the vehicle is modeled with one wheel in two degrees of freedom. The test is carried out by loading the vehicle including the mass of the vehicle and passengers for each type of suspension, namely soft, medium and hard. Vibration analysis was performed using Matlab Simulink to obtain the acceleration response and deflection response. The vibration response graph shows the comparison of the level of comfort and stability of the vehicle on the road profile modeled in step, impulse and sinusoidal functions. From the simulation results, it is found that the Soft and Medium Suspension can handle vibration very well, especially from the level of response speed for relatively flat roads. Meanwhile, the Hard type of suspension is very good at dampening vibrations for high bumpy roads.
