Damped Vibrations of a Jointed Cantilever Beam,

Abstract

The application of these methods to machine tool frames is restricted by some disadvantages. Visco-elastic layers must be very thick. Discret dashpots are more suitable for the reduction of local vibrations. The optimization of friction damping in the joints requires a non-acceptable loss of stiffness. This paper is concerned with the idea of avoiding this stiffness reduction by additional frictional interfaces. Such interfaces are formed by fastening additional e.g. beam-like elements on the vibrating frame regions. These so-called frictional ledges can be fixed with an interface pressure for maximal damping without any reduction of the machine stiffness.
