Apparatus, systems, and methods for damping movement of a first mass relative to a second mass by magnetically generating induced current are provided. A magnet is coupled to one mass and a nonferrous metallic member is coupled to another mass that moves relative to the first mass. First and second springs are coupled to opposing ends of the magnet, the magnet being positioned between the springs. A guide member channels the magnet as it moves relative to the nonferrous member, the magnet being slidable along the guide member. The magnet is in close proximity to the nonferrous metallic member as the magnet moves. Upon causing movement of the magnet by either mass, the magnet generates an electrical current in the nonferrous metallic member that induces a counter magnetic field that opposes the magnetic field generated by the current to damp movement of the magnet as it moves.

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.

Compression springs, such as helical compression springs, include end portions with selectively contoured inner contact surfaces. The selective contours of the inner contact surfaces may take the form of planar, grooved, concave, or other shaped, non-circular surfaces. In addition, enough of the inner contact surface is contoured to reduce the contact stress and/or stress concentration effects on the adjacent coils when the compression spring is placed under load and the adjacent coil engages or contacts the respective end portion. The selective contouring of the end portions may be accomplished by holding the spring in a holder and moving a cutter relative to the end portion of the spring to remove the desired amount of material from the end portion.
The present invention relates to dual-spring assembly that may be employed in cooperation with a damper unit to form a shock absorber. The spring rate of at least one of the springs is adjustable with a preload mechanism, which in turn is movable relative to the damper unit. Further, the dual-spring assembly includes two compression springs arranged in series and each having selected, but different spring rates. The first spring primarily absorbs the energy of applied loads that are below a first amplitude or threshold of applied load. Once the applied loads exceed the first amplitude of applied load, the dual-spring assembly operates with an effective spring rate to absorb the energy of applied loads that exceed the first amplitude of applied load. After a second spring of the dual-spring assembly achieves a desired amount of deflection, the first spring continues to absorb energy from the applied loads.
