Elastic metamaterial shaft with a stack-like resonator for low-frequency vibration isolation
Journal of Physics D: Applied Physics, 2019This paper presents an elastic metamaterial shaft with a new class of stack-like resonators consisting of bonded periodically annular rubber and lead rings that support the formation of ultra-low-frequency vibration band gaps because of reduced stiffness

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

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 ...

The input torque vibrations (i.e. the fluctuations or ripples) induced by internal-combustion engines is a significant source of noise, vibration and harshness issues, which cause problems in automotive powertrains. This is because the torque vibrations are primarily transmitted to the input shaft of automotive transmissions (e.g.
