Problems solved by technology
[0003] The purpose of the present invention is to solve the problems of the existing vibration reduction methods such as insignificant vibration reduction effect, sluggish vibration reduction method and low stability, etc., and propose a fast vibration reduction method for the in-place vibration of digital equipment such as machinery, electronic manufacturing equipment, and industrial robots. In the method and its device, by changing the viscosity coefficient of the magnetorheological fluid in the magnetorheological damping element, the running resistance of the moving mechanism connected to it is increased in the positioning vibration stage, the vibration amplitude of the moving mechanism is rapidly reduced, and the mechanism is shortened. positioning stabilization time

A method and device for reducing vibration of a moving mechanism based on a magneto-rheological damping element, including a vibration-damping element for reducing the vibration of the moving mechanism, a base for placing the moving mechanism and the vibration-damping element, and for detecting the operating state of the moving mechanism The position detection element and the position information and the control system vibration damping element for controlling the motion mechanism and the vibration damping element are installed on the base and connected with the motion mechanism; the position detection element is installed on the base and the motion mechanism Above; the damping element is a magneto-rheological damping element. The present invention proposes a fast vibration reduction method and device for digital equipment movement mechanisms such as machinery and electronic manufacturing equipment. Aiming at the vibration law and vibration mechanism of the movement mechanism, it is proposed to change the magnetorheological fluid in the magnetorheological damping element The viscosity coefficient increases the running resistance of the moving mechanism connected to it in the positioning vibration stage, quickly reduces the vibration amplitude of the moving mechanism, and shortens the stabilization time of the mechanism positioning.

technical field [0001] The invention relates to the technical field of a device for counteracting the in-position vibration of a motion mechanism of industrial manufacturing equipment, in particular to a method and device for reducing vibration of a motion mechanism based on a magneto-rheological damping element. Background technique [0002] The motion systems of digital equipment such as machinery, electronic manufacturing equipment, and industrial robots continue to develop, and the requirements for high-speed and high-acceleration of their motion mechanisms are also constantly increasing. However, the high-speed and high-acceleration requirements make the vibration problem of the motion mechanism more prominent. The large impact force of high acceleration will inevitably bring about complex vibration problems, and the large vibration amplitude and long stabilization time will affect the performance and work efficiency of the motion mechanism. to influence. It is a direc...
