중형트럭 현가계의 설계변수 변화에 따른 피칭운동이 민감도 해석 = A Sensitivity Analysis of Pitching Motion with varying Suspension Design Parameters of Medium Truck

다국어 초록 (Multilingual Abstract)

Ride quality of medium truck became an important item, due to increase the standard of life style. This study describes how to determine and evaluate design parameters related to chassis suspension system through time and frequency analysis. The spring stiffness and damping force of the chassis suspension system were obtained by the magnitude of the vertical acceleration PSD. The simulation was carried out on the various road profile, which is suggested by ISO. The body pitching of medium truck item which should be studied for ride quality. We made truck model by use of DADS, which is dynamic analysis software, in order to find out the truck motions. From the results of sensitivity analysis of suspension parameters,we found out that, the spring and shock absorber affect the pitching of the medium truck. In order to truck model validation, We carried out actual test.<br/>
