Abstract : This research applies recent advances in kinematics, using fundamental models of dynamics, coupled with experimental observations in order to develop methods capable of predicting the performance as well as motion characteristics of certain basic intermittent-motion mechanisms which are useful in industry and military applications. These methods were applied to a selected group of mechanisms, such as Geneva, ratchets and escapements. The analytical part of this research involves: investigation of the kinematic and dynamic performance characteristics of these selected mechanisms; formulation of a dynamic model of impact; determination of the dynamic response of this model under various operating conditions; and development of unit computational programs for analyzing the kinematic characteristics and dynamic response of these intermittent-motion mechanisms. The experimental part of the research involves measurements of the kinematic and dynamic response, and stresses of high-speed external Geneva mechanisms. The purpose of the measurements is to correlate with analysis and to verify the results of theoretical findings. The theory developed in the high-speed intermittent-motion mechanisms was extended to two related areas of mechanism design problems: the momentary-dwell type of intermittent-motion mechanisms which have potential application to the high-speed automatic weapon system; and an investigation on the workspace of a robotic manipulator system.
