A Study on Dynamic Errors of High Speed Press Mechanism with Clearance

摘要

The present paper focuses upon the dynamic errors of high speed press mechanism with clearance. Based on a continuous contact model, the clearance at joint is treated as a rigid linkage, whose length equals the radial clearance and has no mass. The dynamic equation for high speed press is developed via the kinetics universal equation. By comparison of the results between the computer simulation and experimentation computer simulation, clearance and its size as well as the spinning speed of crank are further analyzed concerning the impacts on both the output error and the kinetic responses of high speed press. The investigation is of great significance to the accuracy design of high speed press.
