The Generalized Principle of Inertia Match for Geared Robotic Mechanisms

Abstract numerical examples to demonstrate the principle. The principle of inertia match has been extended from one-degree-of-freedom(D.0.F.) system to multi-D.O.F. systems. Based on the concept of maximum acceleration capacity, a methodology for the determination of gear ratios in geared robotic mechanisms has been developed. It is found that, at the optimum design, the mass inertia matrix of the input links reflected at the joint-space is equal to that of the major links, and the maximum acceleration capacity is independent of the gear train arrangement. Several two-D.O.F. geared robotic mechanisms have been used as design examples to illustrated the principle. Using this methodology, mechanisms can be designed to yield optimum dynamic performanCe. I
