Abstract
A single drive shaft simulator and method is disclosed that allows up to four independent actions to be imposed on a test specimen such as an artificial joint specimen. These motions about mutually orthogonal axes are provided, and a constant compressive force and/or dynamic force may also be applied. The mechanical simulator is simple, accurate, and robust. The simulator assures synchronous movement where amplitude and profiles of the motion can be independently adjusted.
