In the study of vehicle suspensions, simplified models of their dynamics are commonly used, often limited in terms of the number of degrees of freedom and the range of possible applications. Simplifications also concern the lack of consideration for suspension kinematics, which leads to the use of so-called equivalent suspension stiffness and equivalent suspension damping coefficients in the models. The authors of this article analyzed the method of determining the relationship between the computational parameters of the suspension and the characteristics of actual damping elements. The results of relevant studies and analyses concerning an example passenger car are presented in the article.During the analysis of car dynamics, simplified models are often used. Due to the fact that these models are frequently and widely described in the literature, ready-made, derived equations of motion are used, selecting only in a simplified way (…)
