Abstract

A method for determining coil spring force line range corresponding to specific damper friction values using a universal spring mechanism (30) and using the determined force line range (74) in coil spring design. The method includes securing the mechanism to a suspension system including a damper (42), providing a controller (78) for controlling actuator legs (38) thereof for exerting force between upper (34) and lower seats (36) of the mechanism, and performing a capability study of the mechanism. The method further includes determining a desired coil spring force line position based upon the capability study, activating the mechanism to generate a desired coil spring force line based upon the desired coil spring force line position, performing damper friction measurements for determining a coil spring force line position for minimizing damper friction, determining the coil spring force line range based upon the damper friction measurements, and designing a coil spring based upon the coil spring force line range.
