Sensitivity analysis of parametric errors on the performance of a torsion quasi-zero-stiffness vibration isolator

International Journal of Mechanical Sciences, 2017
Abstract A quasi-zero-stiffness (QZS) isolator can perform a good function of low-frequency vibration isolation, but its designed ultra-low dynamic stiffness could be notably affected by parametric errors, which usually occur in the manufacturing and assembling process.

Torsional vibration analysis of a planetary gear type antiresonant vibration isolator using transfer matrix method, Part I: System modeling

Journal of Mechanical Science and Technology, 2020
Recently, a new type of vibration isolator called a dynamic antiresonant vibration isolator (DAVI) has been studied for torsional systems as well as translational systems. In the DAVI for torsional systems, the inertia coupling for the anti-resonance effect is generated by a planetary gear that connects control inertia and inertias at the input and ...

Using Specimen Geometry to Isolate Flexural and Torsional Vibration Modes During Sonic Resonance

Journal of Testing and Evaluation, 2016
Abstract The ASTM E1875 method of sonic resonance is a convenient means of obtaining the elastic material properties of materials, particularly at high temperatures. The technique is performed by exciting a rectangular bar specimen to vibrate over a range of frequencies while measuring the amplitude of the bar’s vibrations.

Experimental and simulation study on the vibration isolation and torsion elimination performances of interconnected air suspensions

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2015
This paper extends recent research on the dynamic performance of an interconnected air suspension. Although some aspects of the dynamic performance of such suspension systems have been studied, little attention has yet been paid to the torsion elimination performance or to the way in which the form of interconnection influences the interconnecting ...

Torsional vibration isolating motor mounting system, mounting arrangement, assemblies including the same

The Journal of the Acoustical Society of America, 1986
Motor vibration isolating arrangements and systems using such arrangements are disclosed. In preferred arrangements, leaf spring mounting arms have low torsional spring constants and yet strength to withstand shipping and handling loads. The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so

Study and Simulation of Isolation Performance of Torsional Vibration of DMF-CS with Centrfugal Pendulu-Type Absorber

2012
The structure of DMF-CS with centrifugal pendulum-type absorber was analyzed, and the kinematics differential equation of DMF-CS was set up by using Lagrange principle. The natural frequency of pendulum was deduced and found proportional with the rotate speed of the second flywheel.
