Abstract

The invention belongs to the technical field of damping and vibration reduction, and in particular relates to a stacked vibration damping mechanism based on a tuned mass damper, which may include only one stacked tuned mass damper or multiple stacked tuned mass dampers. The control range effect of the vibration damping mechanism is roughly adjusted by selecting different numbers of upper masses, and the control range effect of the vibration damping mechanism is finely adjusted by turning the nut. The invention has a simple and compact structure, can realize precise control of the position of the control point, has a large adjustable control range, can realize two-level adjustment, is convenient for recording and repeated operations, and has good vibration reduction effect and adaptability.

Description

technical field [0001] The invention relates to the technical field of damping and vibration reduction, in particular to a stacked vibration damping mechanism based on a tuned mass damper. Background technique [0002] Strong vibrations are very harmful to production activities, scientific research and daily life. In the field of mechanical processing, strong vibration during processing will not only reduce the processing quality and processing efficiency of the workpiece, but also damage the physical and mental health of on-site workers. Therefore, vibration reduction technology in industry has been researched and improved by many engineers and mechanics. Implementations of vibration reduction techniques generally fall into three categories: suppression of vibration source strength, vibration isolation, and vibration suppression. [0003] For example, in the vibration elimination device and strategy disclosed in CN106271861A, the purpose of vibration elimination is achiev...
