Computer-aided curvature analyses of planar four-bar linkage mechanism

A computer-aided curvature analyses program of the planar four-bar linkage mechanism is presented. The complete kinematics curvature analyses of the planar four-bar linkage mechanism depend on the variation of input link angle, angular velocity and angular acceleration are performed by this program. Since the kinematics analyses are routine works, the animation programming is needed. This paper presents an animation program based on the curvature theory for the planar four-bar linkage mechanism.
