Problems solved by technology

However, thin-plate components are prone to vibration during use, which will aggravate the fatigue and wear of the components and affect the safety and normal use of the structure.
The traditional passive control method applies passive damping to the thin plate by pasting the damping sheet to achieve the vibration suppression effect, but the control of low-frequency vibration is not good
[0003] The active vibration control method of the flexible thin plate is to paste the piezoelectric sensor and the piezoelectric actuator symmetrically on both sides of the thin plate. The piezoelectric sensor collects the amplitude signal. It applies active damping to the thin plate to achieve the vibration suppression effect, but for high-frequency vibration, it needs to consume a lot of energy

Abstract

The invention discloses a flexible sheet active and passive mixed vibration controller, belongs to the technical field of inhibition of the vibration of flexible sheets, and aims to control the vibration of the flexible sheets. The flexible sheet active and passive mixed vibration controller comprises a flexible sheet, a damping piece arranged on the flexible sheet, a piezoelectric actuator arranged on the flexible sheet, a piezoelectric sensor arranged on the flexible sheet, a driving power supply connected with the piezoelectric actuator, a data acquiring card connected with the piezoelectric sensor, and an upper computer connected with the driving power supply and the data acquiring card. The flexible sheet active and passive mixed vibration controller saves the energy at high frequency, and still achieves an excellent vibration inhibition effect at low frequency, so that the excellent inhibition effect can be maintained in a wider frequency range.

Description

technical field [0001] The invention belongs to the technical field of suppressing the vibration of a flexible thin plate, and relates to a vibration controller, in particular to an active and passive hybrid vibration controller for a flexible thin plate. Background technique [0002] Thin plate has the characteristics of two-dimensional structure, light weight and less consumables. It is an excellent structural component and is widely used in various engineering structures. However, thin-plate components are prone to vibration during use, which will aggravate the fatigue and wear of the components, and affect the safety and normal use of the structure. The traditional passive control method pastes the damping sheet to apply passive damping to the thin plate to achieve the vibration suppression effect, but the control of low-frequency vibration is not good. [0003] The active vibration control method of the flexible thin plate is to paste the piezoelectric sensor and the p...
