Overrunning modes will be modeled with all the spring elements in a non-CF induced field in order to analytically determine normal forces applied. Transitions, fits, tapers, outer case thickness/wall will be varied to minimize stress and wear surfaces. The specific outcome of Phase I is to use the high fidelity modeling to assist in detecting wear, heat generation zones and high stress areas in the clutch design.
