The Uniformly Tapered Circular Beam as a Dynamic Vibration Absorber.
… texts treat in detail the lumped parameter dynamic vibration absorber. Typical examples are the translating mass vibration absorber, the pendulum vibration absorber, and the bifilar pendulum vibration absorber. The common characteristic of these single degree-of-freedom subsystems is that …

A dual reaction-mass dynamic vibration absorber for active vibration control
Traditional dynamic vibration absorbers (DVAs) consist of a mass-spring-damper system and are an effective means of attenuating structural vibration over a narrow frequency band. The effective bandwidth of the DVA can be increased by the addition of an externally controlled force, generally applied …

A multi-frequency induction heating system for a thermally triggered gel polymer dynamic vibration absorber
… in the early part of the twentieth century, the dynamic vibration absorber (DVA) has played an important role in vibration suppression. In its simplest form, a dynamic vibration absorber is a mechanical network consisting of a spring, a mass and sometimes a damping element. These networks have …

Vibration analysis of a beam structure attached with two dynamic vibration absorbers
… load primarily in flexure that may experience vibration as it does carry vertical loads and gravitational forces. Its exposure to vibration can lead to excessive deflections and failure of to the structure. The aim of this research is to develop the application of dynamic vibration absorber on …

Vibration simulation of a simply-supported beam with attached multiple absorbers
In general, the standard solutions to reduce the vibration and noise problems are to redesign and modify the system such as adding the thickness of wall panels, enhancing the elasticity of the structure and increase the damping mechanism of the structure. In this study, the concept of dynamic …

The Uniform Hanging Cable as a Translational Vibration Absorber.
The small, lateral vibrations of a system consisting of a uniform cable suspended from a mass in a gravitational field and having a lower end mass are considered in this thesis. The frequencies and modal configurations for free vibration were determined. Secondly, a harmonically varying forcing …

Effect of sound radiation from plate attached with absober
… have potential to contribute to substantial vibration and sound radiation, which lead to excessive noise. So, the study was carried out by determine the sound pressure radiated from simply support plate (SSP) without absorber and compared with attached single absorber in term of vibration …

Utilizing Distributed Vibration Absorbers to Reduce Noise Transmission Through the Windshield of a Cessna 150
… contradicts the original assumption that engine vibration contributed to large noise transmission into the cabin of the aircraft via the firewall. Airborne noise and some exhaust noise transmit through the firewall, but not near as much as noise that transmits through the windshield. Reducing …

Internal Resonances in Vibration Isolators and Their Control Using Passive and Hybrid Dynamic Vibration Absorbers
… they only discussed this problem in terms of vibration based on single degree-of-freedom (SDOF) models. These studies did not reveal the importance of the IRs, especially from the perspective of the noise radiation. This dissertation is novel compared to previous studies in the following ways: …
