Steer Feel Evaluation Method by Application of "Analytical Method of Equivalent Linear System Using the Restoring Force Model of Power Function Type"

An “Analytical Method of Equivalent Linear System Uning the Restoring Force Model of Power Function Type”, which is used as a non-linear vibration analytical method for vibration systems that shows their characteristics of viscoelasticity, was applied experimentally to vehicle dynamic analysis. This article describes the theory of this analytical method. The analytical method was applied to vehicle dynamic analysis by using it experimentally to analyze vehicle steering force characteristics. We were able to verify the appropriateness and accuracy of this method.
