To improve vibration damping properties and workability of installation onto steel vibrating objects such as railway steel bridges, the authors have developed a magnetic rubber damper with a constraining layer (MRDC), which consists of a constraining layer made of steel and a magnetic rubber layer. The damping property of MRDC is substantially caused by the frictional loss which arises between the magnetic rubber layer and the steel object. To make clear the damping property of MRDC practically, an equation to calculate the loss factor of a steel plate fully and partially covered with MRDC is derived based on theory of flextural vibration. And, to examine that the proposed theory is proper, measurement of vibration mode and loss factor by resonance method. As the result, the measured values agree with calculated values on each vibration mode.
