Vibration isolation performance of a beam clamped with torsional quasi-zero-stiffness isolator

Journal of Vibration and Control, 2023
Elastic beam structures connected by hinges are a common basic component of many mechanical systems. In this study, the nonlinear transverse vibration of a beam with one end free and the other end simply supported with a torsion spring is investigated.

Performance of magnetorheological elastomer based torsional vibration isolation system for dynamic loading conditions

Journal of Central South University, 2020
Vibration isolation is an effective method to mitigate unwanted disturbances arising from dynamic loading conditions. With smart materials as suitable substitutes, the conventional passive isolators have attained attributes of semi-active as well as the active control system.

Next Generation Torsional Vibration Isolation Tool Increases BHA Reliability Proven by Field Operations in North Sea

Abu Dhabi International Petroleum Exhibition & Conference, 2021
Abstract High Frequency Torsional Oscillations (HFTO) generate high torsional loads in the BHA causing cracks, damaged electronics or twist-offs. A new Torsional Vibration Isolator tool (TVI) protects the BHA by restricting vibrations to the tools between bit and TVI.
