THE DEVELOPMENT OF SYSTEM FOR ANALYSIS OF MOTION IN PLANE  FOUR BAR MECHANISM BASED ON MATLAB SOFTWARE
Abstract
A mathematical model of motion analysis was established in plane four - linkage , and analytical software was developed. The software adopted Matlab as a design language. It combined parametric design with interactive design and had good interface for user. Thus, it was faster and more convenient to analyse linkage. The analytical result was obtained as soon as input parameters was imported and the devisers can make decision - making of modification by the comparing analytical result with design demand. It provides an applied software and method for linkage.
