PURPOSE:To quantitatively measure the adhesion between a rubber stress cone and an insulator over the entire periphery thereof in an actually assembled state by inputting an ultrasonic wave to the contact interface of the rubber stress cone and the insulator and propagating the same as an interfacial wave to measure the attenuation quantity thereof. CONSTITUTION:A predetermined wt. 6 is placed on a rubber stress cone 2 to set the rubber stress cone 2 so as to apply surface pressure to a taper part 5. In this state, an ultrasonic wave inputting contact 3 is mounted on one end of an insulator 1 and an ultrasonic wave detecting contact 4 is mounted on the other end thereof in opposed relation to the contact 3. An ultrasonic wave is inputted and the attenuation quantity of the interfacial wave propagated through the interface of the rubber stress cone 2 and the insulator 1 is measured. By this method, the adhesion between the rubber stress cone and the insulator can be measured in an actually assembled state. |
