In order to increase the reliability and efficiency of the dynamics modeling and analysis for complex planar multi -body systems containing grooved sheave, the corresponding vector bond graph procedure is proposed. From the kinematic constraint condition, the vector bond graph model of point - linear follower is built, which is suitable for inner and external grooved sheave. Based on this, the procedure to mode planar multi - body systems with grooved sheave by vector bond graph is made. For the algebraic difficulties brought by differential causality and nonlinear junction structure in dynamics modeling of the planar multi - body systems, the effective deeoupling method is proposed. By using the corresponding algorithm, the computer automatic modeling and dynamics analysis of the planar multi - body system containing grooved sheave on a computer is realized, its validity is illustrated.
