Abstract: A vibration and shock isolator may include a resilient member and a compressing member. The resilient member may be connected between a vibrating source and an object. The compressing member may provide the resilient member with a compression displacement in accordance with the vibration characteristics applied to the resilient member from the vibrating source to change stiffness of the resilient member. Thus, a designed natural frequency of the isolator may be simply changed using the shape memory wire to suppress vibration amplification. As a result, the isolator may effectively relieve the shock and the vibration so that a structural stability of a structure may be ensured. Further, the isolator may have a simple structure so that the isolator may have improved reliability and durability.
