Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To quantitatively measure the non-linear modulus of elasticity of a viscoelastic material with high accuracy by driving an exciter so that the output of a strain gauge or a load gauge becomes a sine wave free from higher harmonic strain. SOLUTION: A servo motor 5 is rotated to apply initial tension to the sample 15 set to the inside of a thermostatic tank 3 and the output of a sine wave generation circuit 12 is applied to an exciter 2. The sine wave signal proportional to the deformation generated in the sample 5 is detected to be subjected to data processing to calculate the modulus of elasticity. At this time, if amplitude is made large, the detection waveforms of the strain gauge 1 and the load gauge 4 begin to strain and a higher harmonic component appears. Herein, the output of the stray amplifier 6 on the side of the strain gauge 1 is returned to the strain feedback circuit 16 of a vibration control circuit 11 and the component controls a sine wave in order to become only a primary component to apply the same to the vibrator 2.  By this constitution, the non-linear complex modulus of elasticity is obtained from the output of the stray amplifier 9 on the side of the load gauge 4. Contorarily, when the output of the amplifier 9 is returned to the force feedback circuit 17 of the control circuit 11, non-linear complex compliance is obtained from the output of the amplifier 6.
