Self-tuning vibration absorber and vibration reduction method thereof

Abstract

The invention provides a self-tuning vibration absorber, and belongs to the technical field of vibration absorbers. The self-tuning vibration absorber comprises a driving device and an execution unit; the driving device is arranged on a controlled system and electrically connected with a signal acquisition unit arranged on the controlled system, a guide device is arranged on the driving device, a lower supporting block is arranged at the end close to the driving device, the guide device penetrates through the lower supporting block, an upper supporting block is arranged at the top end of the guide device, and the driving device is used for driving the lower supporting block to move; and the execution unit comprises at least four sets of bent plate springs arranged in a circumferential array, at least one set of mass blocks are symmetrically arranged on the two sides of each set of bent plate springs, and the top end and the bottom end of each set of bent plate springs are connected to the upper supporting block and the lower supporting block respectively. According to the self-tuning vibration absorber, the defects that a passive vibration absorber is narrow in vibration absorption frequency band, poor in vibration reduction effect and the like can be overcome, and meanwhile the self-tuning vibration absorber has the advantages of being small in energy consumption and high in stability compared with an active vibration absorber.

Description

technical field [0001] The invention relates to the technical field of vibration absorbers, in particular to a self-tuning vibration absorber and a vibration reduction method using the self-tuning vibration absorber. Background technique [0002] Vibration control is to suppress the vibration of the main structure through different technical means. The most commonly used vibration control categories are: vibration control of vibration source, damping vibration reduction, dynamic vibration absorption and vibration isolation, etc. [0003] Controlling the vibration of the vibration source refers to reducing or eliminating the vibration source from the process and technology, which is the fundamental measure to prevent vibration. For example, use a range hood or a hydraulic press instead of an air hammer. The method of using certain techniques to dissipate the energy of solid vibration in the damping layer as much as possible is called damping and vibration reduction. It is m...
