Dynamic Model of a Crank Press in the Process of Braking

Abstract

The paper studies the dynamic of a brake of crank press. At present, the dynamic research of brake of the crank presses, with account of interaction with other links, is a priority. The crank press contains movable parts and links, the mass of which is from one hundred kilograms to several tons. These parts and links are cyclically stopped when braking with a crank press almost instantaneously, and they are subject to high dynamic loads. To simulate and analyze the movement of crank press with brake, a software package: SimulationX is used. SimulationX is a software package for modeling and analyzing the dynamics and kinematics of cars, industrial equipment, electric, pneumatic and hydraulic drives, hybrid engines, etc. As a result of dynamic calculation, important dynamic parameters of the crank press brake and working ram are determined. It is shown that dynamic loads sharply increase almost in all links of the crank press when the brake is switched on.
