Abstract
This paper considers the derivation of a common 2d automotive suspension heave and pitch design model involving the front and rear axle coupled and uncoupled spring stiffnesses. Many rules of thumb are used in automotive design regarding this model perhaps without full appreciation of the mathematical analysis and assumptions invoked in their formulation. With the widespread use of computer aided suspension simulation models it is perhaps timely to note the derivations of the model equations and the limiting assumptions for which they can be applied with confidence. In particular the derivations and numerical examples show that the concept of a stationary pitch ...
