Occurrence Mechanism and Suppression Method for Shudder in Automatic Transmission Powertrain
International Journal of Automotive Engineering, 2014 Shudder occasionally occurs in the lock-up clutch of automatic transmissions when the frictional characteristics of the lock-up clutch have a negative slope with respect to the relative slip velocity. This study evaluates the effect of a dynamic absorber

Characteristics of adjustable dynamic vibration absorber
Nihon Kikai Gakkai ronbunshu, 2018 One of effective ways to suppress vibration of a mechanical system is using a dynamic vibration absorber. The dynamic vibration absorber consists of a mass, a spring and a damper.

Dynamic Absorbers for Rotating Machinery
, 2015 Dynamic absorbers are simple passive devices installed on mechanical systems to absorb and dissipate kinetic energy, thus reducing the amplitude of vibrations/oscillations. The most widely spread typologies of dynamic absorbers belong either to the family of the Tuned Mass Dampers (TMD) and Tuneable Liquid Column Dampers (TLCD).

Dynamics of a Cubic Nonlinear Vibration Absorber
Nonlinear Dynamics, 1999 Abstract We study the dynamics of a nonlinear active vibration absorber. We consider a plant model possessing curvature and inertia nonlinearities and introduce a second-order absorber that is coupled with the plant through user-defined cubic nonlinearities.

EXPERIMENTAL SPECIFICATION OF THE IMPACT OF MECHANICAL PARTS AND HYDRAULIC OIL CONDITION ON VEHICLE SHOCK ABSORBER PERFORMANCE IN ENERGY DISSIPATION [PDF]
Proceedings on Engineering Sciences, 2019 The purpose of a damper, or so-called ‘shock absorber’, is to introduce controlled friction into the suspension system and dissipate the incoming-to-vehicle energy due to external excitations, in order to give dynamic stability to the vehicle. As damping

Development of rolling pendulum type dynamic absorber using magnetic damping
Nihon Kikai Gakkai ronbunshu, 2018 Purpose of this paper is to reduce the response of rocking vibration mode of vertically isolated equipment. The rocking vibration is the motion that the top of equipment vibrates as the fulcrum in a bottom end.
