Kinematical and dynamical analysis of MacPherson suspension using displacement matrix method

In this paper, kinematics and dynamics of the MacPherson suspension are studied. Displacement Matrix Method is utilized for this purpose. Camber and toe angle alterations are derived by means of the rotation matrix. Kinematical characteristics of the MacPherson suspension are displayed as functions of time and the wheel vertical displacement. Relations for velocities and accelerations of key points are also obtained. Since internal forces and external forces are important in stress analysis and for comfortability, these forces are calculated as functions of time as well. Subsequently, a general analysis of the mechanism under the wheel sinusoidal displacement is presented together with relevant figures and results. © Shiraz University
