シリコーンゲルを用いたばね-質量系のインパルス応答

抄録

Impulse response has been studied in the spring-mass system in which silicone gel was incorporated. The dynamic characteristics of silicone gel were investigated experimientally. The results indicated that the coefficient of viscous damping and the stiffness varied with frequency and compression ratios. The silicone gel with established characteristics was installed to a spring-mass system. From the experiments under various compression ratios of the silicone gel, the impulse responses of this system were obtained. The results indicated that the responses decrease rapidly, compared with a conventional spring-mass system and differ in the compression ratios of the silicone gel. The impulse responses were calculated using the dynamic characteristics obtained experimentally. The calculated response waves and those obtained experimentally were similar in magnitude and decay.
