A Linear Particle Chain (LPC) impact damper is a newly developed passive vibration control device. It is an extension for the commonly used conventional (single unit) impact damper. In this paper, experimental investigations are conducted to examine the efficacy of the LPC impact damper in attenuating the free vibrations of single degree of freedom structures. The experiments’ outcomes clearly indicate the significant effect of the LPC impact damper in suppressing the structure vibration compared to the conventional impact dampers.

First Order Perturbation

A passive vibration control system for the quenching of undesirable self-excited vibrations in mechanical systems is presented. The system is a Lanchester damper, attached to the main self-excited system; a van der Pol oscillator. A first-order perturbation solution shows that complete quenching of self-excited vibration is possible. The result is verified by numerical integration of the governing differential equations. Furthermore, the damper is shown to be effective in suppressing forced self-excited vibrations.

Abstract Due to an increased flexibility of modern mechanical and structural systems, effective vibration control becomes essential to their high-precision operations. In this paper, dynamics and vibration control of a rotating multi-link are studied. Passive vibration control of the link with distributed viscoelastic layers is studied. Effectiveness of the distributed viscoelastic dampers with various stiffness and damping properties is investigated.
