PURPOSE:To ensure high-precision load measurement, by arranging a sound shielding material between an exciting shaft and an attaching part of a load detector and cutting off the propagation of an acoustic energy generated from an oscillation generating machine to said attaching part. CONSTITUTION:A sound shielding material 15 is arranged between an exciting shaft 5 of an oscillation generating machine 1, which excites a test piece 11, and an attaching part 10 of a load detector 9 which detects the load applied to said test piece 11. By this constitution, the sound shielding material 15 cuts off the propagation of said acoustic energy to the attaching part 10 to prevent the generation of acceleration of the detector 9. As the result, the excitation of the attaching part 10 due to said energy is not generated, and consequently, the generation of acceleration of said detector is prevented to ensure the load measurement of very high precision. |
