KINEMATIC-DYNAMICAL OPTIMIZATION OF THE FOUR LINKS SUSPENSION MECHANISM FROM CAR BODY’S ROLL MOTION CRITERION

Abstract

Considering four variants of the four links mechanisms used in passengers cars suspensions, on the basis of Matlab and ADAMS-View softwares, a series of kinematical and dynamical analyses are realised with the target of making evident the influence of the roll center position and roll centroides forms on the parameters of the automobile frame roll motion. There are seeked: roll motion centroids, roll angle, roll angle velocity, roll angle acceleration, lateral displacement of the center of gravity of the automobile’s frame.
