Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a vibration absorber through nonlinear energy transfer and collision energy consumption, which has a simple structure, reasonable design, convenient use and operation, and good vibration absorption effect. It effectively solves the problem that the three control methods of active control, passive control and active-passive joint control in the existing technology are not ideal. It can quickly and effectively reduce the vibration generated by structural parts, and at the same time does not require any external energy supply. The vibration reduction efficiency is high and the application wide range

Description

technical field [0001] The invention relates to a vibration absorbing device, in particular to a vibration absorber for suppressing the vibration of various mechanical equipment structural parts through nonlinear energy transfer and collision energy consumption. Background technique [0002] Vibration is a form of motion that is inevitably generated during the operation of various mechanical equipment. Vibration will lead to premature fatigue failure of structural parts of mechanical equipment, abnormal movement of structural parts, inaccurate positioning, and noise. Therefore, the vibration suppression of structural parts has become an effective way to improve equipment movement accuracy, service life and reduce noise. [0003] At present, there are usually three ways to suppress the vibration of structural parts, namely active control, passive control and combined active and passive control. Among them, active control is to analyze the possibility of target deviation in ...
