O-Solution DS-5000
The loss coefficient and Young's modulus (longitudinal elastic modulus) of the damping material itself are calculated from the measurement results of the multi-layered test specimen using the formula described in JIS K7391.
The loss coefficient is one of the indicators used in the fields of mechanical vibration and polymer materials to show vibration damping performance. Damping materials with a large loss coefficient are used by being attached to the surface of structures for the purpose of reducing vibration and radiated noise. This tool calculates the loss coefficient and Young's modulus of the damping material itself from the frequency response function of a multi-layered test piece (a test piece with damping material attached to a base material) measured with the frequency response measurement software OS-4100, thereby clarifying the vibration damping performance of the damping material.
