Abstract

Aiming at the kinematics characteristics of the main drive mechanism of the pressure machine, a triangular toggle rod main driving mechanism of the pressure machine was proposed.According to the working principle of the mechanism, the working principle schematic diagram and simulation model of the triangular toggle rod main driving mechanism were established.According to the geometric relations between connecting rods, the kinematic simulation of connecting rods 1—7 was performed in sequence by kinematics analysis software ADAMS.The curves of displacement, velocity and acceleration of connecting rod with different length were obtained.The motion characteristics of each rod with different lengths were obtained, the influence of each connecting rod on the working state of the main driving mechanism was analyzed, the motion law of the main driving mechanism of pressure machine was revealed.The study provides a theoretical basis for determining the parameters of the mechanism under actual working conditions, and lays a foundation for more in-depth and detailed research on the toggle rod mechanism.
