Abstract

Abstract One can construct vibroisolators by using fluid-saturated porous cylinder elements. The force applied to the vibroisolator must be composed of two parts, those carried by the skeleton and the fluid. Each component moves with its own speed (or frequency) and therefore the separate parts of the applied force are displaced in phase. In such a case the coefficient of the force transmission can be less than unity. Besides this, the fluid-saturated porous cylinder can behave like a shock absorber.
