Simulation of the crank press dynamics by SimulationX software

Abstract

The most important problem of engineering is to increase the productivity of crank presses. Itis necessary to increase press drive working velocities. In result, press’ dynamic loads in linksand its mechanisms sharply increase. Now, the investigation of the dynamics of crank pressesis a vital problem and requires preparation of a dynamic model. A dynamic model selectiondepends on the reliability of the initial information about system parameters and other factors.The preparation of a dynamic model requires preliminary calculations and sometimes experimentalstudies. For the selection of a successful dynamic model of a machine, the researcher must havean engineering intuition, information on previous dynamic calculation, experimental studies andoperating a machine. This paper presents the dynamic simulation of the crank press by usingcomplex SimulationXR⃝software. For simulation of crank press dynamic, an electric motor whichhas 0.5 kW power, 450 rpm rated speed and 4000 N rated load on the slider was considered. Itwas founded that the dynamic loads on links of the crank press increase sharply at the time ofswitching the clutch and clutch moment reach 120 Nm.
