4-POSITION SYNTHESIS FOR SPATIAL MECHANISMS WITH 2 INDEPENDENT LOOPS

Abstract

During the practical implementation of four-position guidance synthesis for the spatial mechanisms, many mathematical models for rigid body guidance design are found to be too complicated to solve especially for up to four positions. Our objectives are to uncover simple and analytical ways to synthesize the single degree-of-freedom, two independent loop spatial mechanisms which are capable of four precision positions. Furthermore, prescribed timing is simultaneously considered for some spatial mechanisms.
