A Method to Analyze “The Imaginary Kingpin Axis” in Multi-Link Type Suspension Systems 930262

The purpose of this paper is to introduce a method to analyze the imaginary kingpin axis in multi-link type suspension mechanisms by using the Displacement Matrix method, the instantaneous screw axis theory, and the nonlinear equation solver “DESIGN”.[1][2]The mathematical logic and a Kinematic theory used in this method have been developed a long time ago. But the key point of this method is how accurate and effective we can get the information on design parameters related to the imaginary kingpin axis existing only in the multi-link type suspension, especially in the initial stage of suspension geometry design.
