Abstract

The invention discloses a device and method for measuring and controlling the vibration of a perforated flexible plate driven by double flexible joints.The device comprises a flexible plate body part and a control part, wherein the flexible plate body part comprises a perforated flexible plate, the upper end and the lower end of the perforated flexible plate are respectively connected with a transmission component through flexible joints, a piezoelectric ceramic sensor, a piezoelectric actuator and an acceleration sensor are adhered to the perforated flexible plate, and the control part is used for detecting vibration signals of the perforated flexible plate according to the piezoelectric ceramic sensor and the acceleration sensor so as to obtain control quantities, and respectively outputting the control quantities to the piezoelectric actuator and the transmission component so as to inhibit the vibration of the perforated flexible plate. According to the invention, the influence of different torsional rigidities on the vibration mode of the perforated flexible plate can be comprehensively researched.

Description

technical field [0001] The invention relates to the field of vibration control of flexible plates, in particular to a device and method for measuring and controlling the vibration of a perforated flexible plate driven by double flexible joints. Background technique [0002] Since the industrial revolution, the automatic manufacturing technology has been more and more developed. Automatic manufacturing is inseparable from manipulators, and these mechanical plates are bulky and considered as rigid link manipulators. However, in modern times, in order to improve work efficiency, reduce energy waste, or carry out precision manufacturing, the lightweight design of mechanical boards has become more and more important. Reducing the cross-sectional area of ​​the mechanical board or adopting a hollow structure are methods for lightweight design. When the mechanical board is lightweight, the mechanical board will have the characteristics of flexibility, and it will face vibration an...
