This article introduces the simulation analysis of the motion characteristics of the die-cutting moving platform system. By establishing a three-dimensional model of the die-cutting moving platform, simulate and analyze the operating characteristics of the die-cutting machine, and grasp the basic characteristics of the moving platform movement. This article simulates the relationship curves between the displacement of the moving platform system and the crankshaft angle, the speed of the moving platform and the crankshaft angle, and the acceleration of the moving platform and the crankshaft angle, and analyzes the characteristics of each motion stage. Combining simulation calculations and mathematical models of a moving platform system can intuitively and accurately analyze and judge the motion characteristics and laws of the moving platform. By analyzing the motion characteristics and laws of the die-cutting moving platform, reference can be provided for the design, manufacturing, and optimization improvement of die-cutting machines.
