Abstract
It has been decade, researchers has been conducting researches on the topics concerning vehicle behavior. Suspension system, driving maneuver and road profile are the particular parameters in order to achieve the aim in vehicle behavior understanding. This paper combined these three criteria by means of using a passenger car equipped with MacPherson strut front suspension undergoes different driving behavior. The objective of this paper is to study the effect of passenger car equipped with MacPherson strut front suspension system vehicle behavior based on different driving maneuvers. For this study, Proton Persona Sedan 1.6 Manual Transmission Base Line was used to investigate the MacPherson strut suspension system. Data were collected using DEWESoft Software. As the velocity and direction varies with time, the vehicle response subjected to stationary excitation, while it varies with different velocity and different type of road. Acceleration, deceleration and bumpy test the suspension mechanism support the weight of the vehicle yet to cushion bumps and holes in the road. It can be concluded that the MacPherson strut suspension system has an effect on not only vehicle behavior but also comfort ride. These findings provide the following insights for future research in suspension vibration in order to optimize the performance of the MacPherson strut suspension system.
Highlights
Road vehicle suspensions producing momentum and guidance forces are essential for driving safety
The test car is equipped with wire potentiometer, accelerometer, GPS, speed, tire slip angle, gyroscope, rotating wheel sensor that connected to the data acquisition system that has been installed with DEWESoft Software to collect and monitor the data
The time response for the acceleration test is longest during the test 90km/h on road that results in 40 seconds
Summary
Road vehicle suspensions producing momentum and guidance forces are essential for driving safety. The suspension system isolates the occupants or cargo from severe levels of shock and vibration induced by the road surface. The suspension system allows the springs and shock absorbers to absorb the energy of the bump, so drivers and passengers can have smooth ride. While doing these two jobs, the suspension system must not allow loose, uncontrolled movement of the tire and wheel and must keep the alignment of the tire as correct as possible [3,4].
