Method for saving energy and attenuating vibration of automated mechanical system having motion-stoppage movement pattern

Abstract

The invention relates to a method for saving energy and attenuating vibration of an automated mechanical system having a motion-stoppage movement pattern. The method has the main characteristics of: picking up kinetic energy of inertial load of a decelerating section in the motion-stoppage movement pattern; storing the kinetic energy in an elastic potential energy way; and releasing the picked and stored elastic potential energy on starting and accelerating sections of the inertial load in the motion-stoppage movement pattern in a driving force or moment applying work way to carry out auxiliary drive to the inertial load so as to greatly reduce the maximum driving moment of the system and reduce energy consumption of the system. The method picks up the inertial kinetic energy of the decelerating section so as to reduce vibrational excitation of the system and further reduce vibratory response of the system. The method eliminates geometric closed gaps of an intermittent mechanism at a stoppage position so as to improve positioning accuracy of an intermittent motion mechanism. Therefore, the method has obvious effects of solving the problem of saving the energy and attenuating the vibration of the automated mechanical system having the motion-stoppage movement pattern, and improving the positioning accuracy.

Description

technical field [0001] The invention belongs to the field of mechanical design theory and method, and relates to an energy-saving and vibration-reducing method of an automatic mechanical system. Background technique [0002] In automated machinery, in consideration of the production process or assembly line beat, the output motion behavior of some automated machinery has the characteristics of motion-stop, such as the feeding and packaging process of chip packaging machinery has obvious motion-stop characteristics. The purpose of the pause is to ensure the packaging quality and performance of the product in the process. For another example, in the post-press processing automatic die-cutting and hot-stamping machinery, it is necessary to transport the hot-stamped die-cut paper to the designated die-cutting and hot-stamping position, and then stop at this position for a certain period of time to carry out die-cutting and hot stamping. The intermittent motion mechanism is the ...

Problems solved by technology

The reason is that when the inertial load starts, the flywheel acts as an inertial load to increase the driving torque of the system, and in the deceleration phase, the flywheel increases the inertia of the system, resulting in aggravated impact
