12.1 Introduction. High vibration levels can cause machinery failure, as well as objectionable noise levels. A common source of objectionable noise in buildings is the vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor.
1. Introduction1.1. Background and motivation. Quasi-zero-stiffness (QZS) vibration isolators, with their unique high-static and low-dynamic stiffness features, show great promise for the design of vibration isolation devices to deliver effective vibration isolation in a much lower frequency range than their linear counterparts.

Vibration Isolation is an engineering principle used to prevent unwanted vibrations and shocks from reaching sensitive equipment or disrupting a controlled environment. This involves the use of specific materials and strategic design. Vibration Isolation is a medical methodology used to minimize muscle tremors in patients.
In this paper the effectiveness of two stage vibration isolation on example of a vibratory conveyor has been shown. Vibratory conveyors are used for separating the casting from the mold in foundries. In the considered case the shake-out conveyor has been supported directly on the foundation. Due to that the high amplitudes of vibrations on …

The improved metamaterial exhibits a superior load-carrying and vibration isolation capacity compared to its traditional counterpart. The bandgap of the proposed metamaterial can be easily tailored through …
The quasi-zero stiffness (QZS) system, as a typical high-static-low-dynamic-stiffness (HSLDS) system, is able to realize low frequency vibration isolation by introducing nonlinear negative stiffness. However, the nonlinearity of the system may result in a serious deterioration of the isolation performance under large amplitude excitation. …
