A semi-active device for the vibration control of machinery foundations or for ride control of vehicles is proposed. A semi-active damper utilising dry friction is employed, with balance logic, a class of sequential damping, being used to minimise the force transmitted. The friction force applied to

โฆ Synopsis
The response of a linear SDOF system subjected to harmonic excitation to which a Tuned Vibration Absorber with linear sti!ness and dry friction damping is attached is considered. Based on an intuitive examination of the physical behaviour of the system, closed-form expressions for TMD optimum parameters and for the steady-state amplitudes of vibration are presented. Two examples allow the comparison between the predicted behaviour and that found by numerically integrating the equations of motion.

The stability analysis for periodic motions of a class of harmonically excited single degree of freedom oscillators with piecewise linear characteristics is presented. The common characteristic of these oscillators is that they possess viscous and constant damping properties, which depend on their v
Some vibration attenuation devices make use of material non-linearity and dry friction damping mechanisms. Such devices are often exposed to a random vibration environment. It is important for engineers to be able to calculate the random vibration response of a system involving these devices, and th
