vibration absorber for projectors

How vibration absorber works Vibration absorber is applied to the machine whose operation frequency meets its resonance frequency. m m a m 1dof 2dof Frequency mass) Operation freq. Vibration absorber is often used with machines run at constant speed or systems with const. excited freq., because the combined system has narrow operating bandwidth.

Vibration Absorbers Project

to produce an undamped tuned vibration absorber based on the spring alone, as is analyzed in Problems 1 - 3, one can also eliminate the spring to produce a vibration absorber based on viscous damping alone called a viscous vibration absorber. Viscous vibration absorbers are less effective than tuned mass dampers, but are simpler to construct.

Parameters Optimization for a Kind of Dynamic Vibration

Jul 10, 2016 A new type of dynamic vibration absorber (DVA) with negative stiffness is studied in detail. At first, the analytical solution of the system is obtained based on the established differential motion equation. Three fixed points are found in the amplitude-frequency curves of the primary system. The design formulae for the optimum tuning ratio and optimum stiffness ratio of DVA are obtained by ...

Properties of Drillstring Vibration Absorber for Rotary

May 12, 2020 During drilling into hard rocks, the vibration of telescopic drillstring for the rotary drilling rig becomes more severe, which not only leads to the fracture of drillstring, but also reduces the rock-breaking efficiency, the service life, and the reliability of the rotary drilling rig. A drillstring vibration absorber for the rotary drill rig was proposed based on nonlinear targeted energy ...
