In order to analyze the kinematic characteristics of working mechanical for mechanical press, the crank toggle mechanism was analyzed on kinematics by the vector-equation analytical method, and the displacement equations of machanism were built based on the closed vector diagram. Then, the velocity and acceleration equations were derived, and the unknown quantities were obtained. Next, the kinematics model was solved and analyzed by numerical analysis method, and the block diagram for calculation program of kinematic equation was designed. Furthermore, the calculation program was written based on the software MATLAB, and the numerical solution of these nonlinear motion equations was conducted. Finally, the toggle swing angles, slide motion curves of displacement, speed and acceleration were obtained, and the graphical process for calculation results was conducted. By these graphically quantitative results, such as limitation of swing angles, the maximal displacement of slide, mean velocity of slide and standard deviation, the rationality of design for the toggle working mechanism could be verified.
