る防振ゴム損失係数計測装置。 An actuator is mounted on the upper end of two layers of vibration-proof rubber with an appropriately sized mass inserted between them, and its operating rod faces the mass, and an actuator is placed above the actuator and operates. A vibrator whose rod faces the actuator, a phase calculator connected to a load cell attached to each of the two actuating rods, and an acceleration pick-up attached to the mass, and the output and a controller for controlling the actuator, and the loss coefficient of the vibration isolating rubber is determined from the phase difference between the control force and the excitation force when the actuator suppresses the vibration of the excited mass. A vibration-proof rubber loss coefficient measuring device characterized by:
