Dynamic Model of Servo Mechanical Press

Abstract

Servo mechanical press is a mechatronic system, consisting of a reducer, actuator and a servomotor with a controller. Control of the servo mechanical press is carried out with a help of the controller depending of technological process of pressing. Reverse kinematic analysis of the actuator of the servo mechanical press is presented in the work to determine the law of motion of a crank, reproducing the specified law of motion of the servo mechanical press slide. Obtained law of motion of the actuator’s crank of the servo mechanical press is necessary to choose the servomotor. Considering that servo mechanical press works by complex programmable motion large dynamic loads occur in its nodal points and links. The work proposes to simulate the dynamics of the servo mechanical press on the software complex SimulationX. Dynamic model of the servo mechanical press is composed with account for elastic-dissipative characteristics of the links and the parameters of the servomotor, for different laws of motion of the slide. A dynamic model of a 50-ton servo mechanical press is developed using the SimulationX software package. Calculation was carried out using real data of the existing 50 ton servo mechanical press. As a result of the calculation of the dynamic model of the servo mechanical press, the following data were obtained: motion, velocity, acceleration of the slide, torque effect on the crank, angular rate, torque effect, power of the servomotor.
