New Vibration System Using Magneto-Spring

Non-linearity of magneto-spring and instability of float control have been used for establishing a new vibration isolator system, in which the polarity of the damping constant can be changed easily. The positive damping is independent of loaded mass, which is a very good characteristic for the suspension system compared with the current mechanical pairs composed of metal- or air-spring and a shock absorber. On the other hand, the negative damping can be used for the excitation device of the simplified construction, which leads to a decrease in cost and weight.
