Abstract

Dynamic performance of a vehicle is the important aspect in designing a vehicle. As for commercial vehicle which is related in delivering passengers and goods, comfort and safety are the crucial characteristics that must be taken into consideration. Three type of test simulation which cover ride, handling and stability criteria were carried out to determine the behavior of the vehicle in real world driving condition. Every test was carried out with different test parameters at different vehicle’s speeds and masses. In the ride criteria, the bounce sine sweep test was carried out to represent the motion of vehicle when travelling on uneven road surface. Then, the handling criteria used double lane change test to represent the motion of vehicle during overtaking on the highway. For the stability criteria, J-turn type test was carried out to represent motion of vehicle when a sharp steering input was applied to the vehicle in an event of avoiding obstacle during emergency situation. All of the results from the tests are analyzed based on different test parameters to determine the difference in dynamic behavior of the vehicle. Higher values of vehicle’s speed and produce higher value of test output results.
