Application of VB in the kinematics analysis of planar four-bar mechanism

Method for kinematics analysis of planar four-bar mechanism based on Visual Basic language is introduced.According to the mathematical models established with a simple and effective method,and using the computer simulation technology,the movement of mechanism can be demonstrated,and the trace of any point on the linkage can be plotted automatically.Moreover,the movement characteristics of mechanism components,such as displacement,velocity and acceleration curves are exported.This method provides a simple approach to analyze the movement of planar mechanism.
