Summary:

A method for measuring spring rate and damping coefficient is necessary for complete laboratory evaluation of a suspension component. This report outlines a technique by which a linear model is adjusted by an analog computer so that its parameters match those of the test specimen. The accuracy of this linear model is good unless the test specimen parameters are very nonlinear.To determine how structural changes in a suspension unit affect the dynamic action of the unit, measurable suspension parameters must be defined. One set of parameters can be obtained by assuming that, for small angular motion, a single suspension unit can be modelled by a parallel springer-damper combination. This system is completely defined by the two parameters spring rate, K, and damping coefficient, D. This paper outlines a method to measure K and D under laboratory conditions which simulate typical operational environment
