Four-bar linkage mechanism motion analysis software design

ABSTRACT

This design is based on MATLAB ,focused on four-bar linkage,withmechanism motion analysis design .four bar linkage is a widely used in all kinds of mechanical installations in the transmission mechanism, is the mechanical transmission in the indispensable component. MATLAB is the international widely used a powerful engineering calculation and analysis software, using the software's powerful computing functions and simulation kit can be easily realized on the organization's motion analysis and simulation.

This design is the application of MATLAB GUI design tools and M program, combination of planar four-bar movement analysis, through the GUI realize interface design, through the M complete programming and commissioning, and through the interface realized four-bar movement analysis and simulation, interface runtime judge the mechanism type and displays the instantaneous velocity follower rod, instantaneous Angle acceleration, crank Angle between the minimum transmission Angle and anyway, stroke ratio coefficient.
