A theory of a simple dry friction element for damping undesirable vibrations and noise of disk shape bodies (as railway or tramway wheels) is elaborated. This anti-vibration structure consists of a wire ring interrupted in one point and with a soft oversize inserted into a circular groove turned in the damped body. In order to reach the optimal damping efficiency, the curvature of wire ring must be variable along its length. The presented analysis is oriented on the aim to design this wire ring curvature to reach constant contact pressure along the whole periphery of groove. Examples of optimal curvature and bending moment distribution are added.
