Intelligent undamped dynamic vibration absorbing system

Abstract

The invention discloses an intelligent undamped dynamic vibration absorbing system. The dynamic vibration absorbing system comprises a control system and a dynamic vibration absorber; the vibration absorber comprises a bottom plate, a lower mass block, an upper mass block and a stepping motor; the stepping motor is mounted on the upper side of the upper mass block; a motor shaft of the stepping motor penetrates through the upper mass block to be connected with a sleeve; a screw rod is arranged on the lower mass block; the upper end of the screw rod is connected with the sleeve; a guiding rod is vertically arranged on each of two opposite sides of the stepping motor; an upper connecting piece is arranged on the lower side of the lower mass block; a lower connecting piece is arranged on theupper side of the bottom plate; the upper connecting piece and the lower connecting piece are connected through an elastic steel plate; and the control system is connected with the stepping motor. Thesystem is simple in structure and convenient to control; the inherent frequency omega0 of the undamped dynamic vibration absorber can be equal to the automatic tracking working frequency omega through control by the aid of the control system, so that the purpose of effective vibration absorbing is achieved; and the whole vibration absorbing system is lower in cost.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to an intelligent non-damping dynamic vibration reduction system. Background technique [0002] During the operation of mechanical equipment, due to the unbalance of rotating parts and other effects, vibration will be generated to varying degrees. Especially for large and medium-sized equipment such as: fans, engines, motors, etc., the strong vibration and noise caused during operation can easily affect product quality and even cause safety accidents that damage machines or buildings. Therefore, during the use of the machine, it is necessary to carry out vibration reduction and vibration isolation treatment on the machine equipment. [0003] There are many existing vibration reduction and vibration isolation methods, and dynamic shock absorbers are one of them; they are divided into two types: undamped dynamic shock absorbers and damped dynamic shock absorbers, and are ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned deficiencies existing in the prior art, the purpose of the present invention is to solve the problems of the existing shock absorber and the vibration-damping system with complex structure, incapable of intelligent adjustment, poor applicability, and high cost, and provide an intelligent non-damping power The vibration reduction system has a simple structure and is easy to control. The natural frequency ω of the undamped dynamic shock absorber can be realized through the control system. 0 Automatically track the working frequency ω, so as to achieve the purpose of effective vibration reduction, and the cost of the entire vibration reduction system is lower
