机械式可控金属压力机建模和仿真分析

new controllable mechanical metal forming press which is driven by a combination of a constant speed motor and a servo motor is investigated in this paper. It offers combined functions including metal blanking, bending, drawing, coining etc. and such a combination cannot be completed by traditional mechanical press. The new controllable mechanical metal forming press also has merits such as energy-saving, high-speed, flexible controllable, simple and compact, and so on. A modeling language for multi-domain physical systems called Modelica is utilized to establish simulation models for the controllable mechanical metal forming press. The models include constant speed motor, servo motor, multi-body mechanicsm, controller etc. Further a trajectory planning function module and an inverse kinematic function module were also programmed. The multi-domain simulation models combine the domains of mechanical, electrical, control in a unified form and hence can perform simulation in a unified platform. Simulation results and analysis verify the effectiveness of the simulation models.
