Abstract
A method for modeling a coil spring on a suspension system in terms of derived torque and force characteristics of the spring comprising the steps of providing a force field generator for simulating the spring, securing the force field generator to the suspension system, activating the force field generator to produce forces for characterizing the spring, measuring the forces; and deriving a spring design based upon the measured forces.

A method for modeling a coil spring on a suspension system in terms of derived torque and force characteristics of the spring comprising the steps of:
- providing a force field generator for simulating the spring;
- securing the force field generator to the suspension system;
- activating the force field generator to produce forces for characterizing the spring;
- measuring the forces;
- measuring the torques;
- and
- deriving a spring design based upon the measured forces and measured torques.
A method for modeling a coil spring in terms of torque and force characteristics to produce a spring design for an automobile suspension comprising the steps of:
- assembling a mechanism having spaced apart moveable platforms and a plurality of actuable links interconnecting the platforms at corresponding joints on opposite ends of each link;
- specifying a kinematics relationship between the platforms and the links;
- applying the mechanism to the suspension system;
- actuating the links to generate corresponding applied forces and torques at each joint;
- measuring the applied forces and torques;
- and
- deriving the force and torque characteristic of the spring to be designed based upon the kinematics and the corresponding applied forces and torques at each joint.
An apparatus for modeling a coil spring on a suspension system in terms of derived torque and force characteristics of the spring comprising:
- a force field generator for simulating the spring, said force field generator secured in the suspension system, and means for activating the force field generator to produce forces therein for characterizing the spring.
