The most important problem of engineering is to increase the productivity of crank presses.It is necessary to increase press drive working velocities.In result, press' dynamic loads in links and its mechanisms sharply increase.Now, the investigation of the dynamics of crank presses is a vital problem and requires preparation of a dynamic model.A dynamic model selection depends on the reliability of the initial information about system parameters and other factors.The preparation of a dynamic model requires preliminary calculations and sometimes experimental studies.For the selection of a successful dynamic model of a machine, the researcher must have an engineering intuition, information on previous dynamic calculation, experimental studies and operating a machine.This paper presents the dynamic simulation of the crank press by using complex SimulationX R ⃝ software.For simulation of crank press dynamic, an electric motor which has 0.5 kW power, 450 rpm rated speed and 4000 N rated load on the slider was considered.It was founded that the dynamic loads on links of the crank press increase sharply at the time of switching the clutch and clutch moment reach 120 Nm.
