Joint Force and Moment Analysis of a Three-Dimensional Suspension Mechanisms 910015

Despite its wide use and many years of engineering research and development, most suspensions, particularly “The McPherson Suspension”, have not been investigated as truly three-dimensional mechanisms.
In this paper the McPherson Suspension, which is modeled first as a three-dimensional guiding mechanism, is analyzed for the forces and moments at each of the joints with its continuous displacement pattern of the suspension, in three dimensional space.
With the development and use of effective software such as “Nonlinear Simultaneous Equations Solver” and “Displacement Matrix Method” this paper, for the first time, presents an analysis of forces and moments of joints of rubber bushings to evaluate accurately the compliance effects.
