The Kinematic analysis, which is the basis of the mechanical design, evaluation of mechanical motion and the dynamic performance, and it is the basic of Analyze Optimal Synthesis of new machinery of existing machinery. the main access to institutions of certain components of the displacement, angular velocity and angular acceleration, and some points of track, speed and acceleration. The Dynamic Analysis, which provides a theoretical basis for Selecting and designing of bearings, parts strength calculation and selection of the original motivation, Constraints derived anti-vice campaign and the drive force (or torque) based on the analysis of kinematics and the Working resistance.In this paper, using vector and matrix theory applicable to the MATLAB / SIMULINK simulation of the crank, RRR Ⅱ class bar group mathematical model of kinematics and dynamics, and using this mathematical model draw up M Function Simulation Module, a RRR four -bar linkage and a RRR-RRR six institutions were taken as example ,the procedures of modeling and simulating. Obtain the deputy of the anti-rotation force and driving torque through the simulation. Its main purpose is to constitute the body of the bar group Simulation Module, building the MATLAB / SIMULINK simulation model for the bar group, to do the kinematic and dynamic simulation and analysis for different types of planar linkage.Keyword: Linkage Kinematics Dynamics MATLAB/SIMULINK SimulationSignature of Supervisor:
