The dynamic characteristics of piping system installed in industrial facilities have to be recognized as one of the significant issues in economic and safety design consideration. Piping systems are generally connected to supporting structures at several points by means of devices such as guides, spring hangers, hydraulic or mechanical snubbers and certain energy absorbers. When friction damper attracts attention, the amount of energy dissipation at contact surface is restricted, because the maximum displacement of sliding motion is limited by the clearance of the equipment. In order to increase the amount of energy dissipation, the ball screw type magnetic friction damper is proposed. This damper is expected to increase the energy dissipation by converting one directional motion to rotating motion by ball screw. In this work, the fundamental characteristics of proposed damper are clarified. The numerical model is made considering parameters obtained from testing, and the results from simulation are compared with the results from testing.
