Abstract
A shim stack testing apparatus and method of determining a stiffness of the shim stick may be employed to assemble a shim stack kit. The apparatus includes a testing jig that receives either a compression or rebound shim stack. The testing jig may be used with a variety of testing machines capable of determining force versus deflection. The test jig includes a simulated piston rod coupled to a simulated piston valve having apertures. The shim stack being tested may be coupled to the piston at a selected location and then deflected by a pre-determined amount by a loading fixture having elongated prongs. Once the pre-determined deflection is achieved, a corresponding force is identified and then an overall stiffness value for the shim stack is obtained. Tested shim stacks may be assembled into kits with each having an identified stiffness that may be compared to a baseline stiffness value.
