This article established the kinematical mathematic
model of the planar mechanism ,which is programmed
and solved with designing the mutual interface of the
calculation by MATLAB.This convenient method is
provided for the complicated calculation of the analysis
and also applicable to the kinematical analysis of the
complex planar mechanism.
A mathematical model of motion analysis was
established in planar four- linkage ,and emulational
software was developed. The software adopted
MATLAB as a design language. It combined parametric
design with interactive design and had good
interfacefor user. Thus,it was faster and more
convenient to analyse linkage. The emulational result
was obtained as soon as input parameters was
