In order to realize the practical use of permanent magnets that have a high coercive force and high residual magnetic flux density, we propose the use the magnet-spring, which can generate the force of 0.67 MPa that happens with the magnetic flux density of 1.3T. The linear characteristics of the metal spring and the non-linear characteristics of the magnet-spring are joined to create a combination spring which has linear characteristics when the spring constant is in a quasi-zero state, under normal conditions of use, but overall is a non-linear spring system. In the magnet-spring, rare-earth magnets are faced so as to repel each other ; it is a vibration control technology that is comprised of repulsive forces created under relative motion, attractive forces, the flux control created by electro-magnetic induction, and the magnetic field gradient. We now offer this report on new characteristics of disturbance cancellation that achieve a non-resonance condition via passive control using the combination spring.
