AUTOMATIC DISPLACEMENT
ANALYSIS OF PLANAR MECHANISMS
WITH MATCHING BASIC KINEMATIC
CHAINS METHOD*
Abstract:
A simple, efficient, automatic and universal method to fulfill displacement analysis of a great deal of mechanisms regenerated by Yan’s mechanism creative theory has been developed. For a regenerated mechanism, at first, the method identifies its type and structure and changes it into a rigid structure by fixing the ground link and the input link. And then this rigid structure is decomposed into a set of basic kinematic chains (BKCs). By matching the type of BKC, the displacement analysis equations can be set up, and all possible configurations, in which positions of all movable links are considered, can be given out.
Key words: Mechanism analysis Computerized method Matching basic kinematic chains |
