Abstract: Aiming at solving the problem that traditional slidercrank press could not meet the requirement of low speed and high efficiency, the characteristic of the traditional slidercrank press was analyzed that the pressure was not easy to control, the technology adaptability was poor, the workpiece was easy to create crack and so on. So the TriangleLink press was investigated in this thesis and the kinematics equation of the TriangleLink press was derived. The ADAMS software was used to establish a TriangleLink mechanism press model, the method of Lagrange equation was used in multirigid body system dynamics theory and the kinematics and dynamics simulation was made. The results indicate that the maximum speed of the slider of TriangleLink decreases 42.4 percent and the maximum acceleration 21.3 percent in comparison with those of slidercrank, quick return characteristics of TriangleLink is 1.9. The inertial forces of the TriangleLink press is less on condition of super high speed, so it meets the requirements of super high press. Each inertial force is relatively small in nominal pressure stroke, so it is quite good to meet the work requirements of the press.
