ABSTRACT:
A sag-compensated vibration isolation mount includes a cylindrical rubber dy element and a circular band extending around the body element. The band is formed from a shape-memory alloy metal which has a predetermined transition temperature. The band is operative for restricting outward bulging and sagging of the body element when the body element is subjected to an axial load at a temperature above the transition temperature. The band has a first length at a temperature above the transition temperature and it is stretchable to a second length at a temperature below the transition temperature. At temperatures below the transition temperature, the body element normally stretches the band to its second length. However, when the band is heated above its transition temperature, the band rapidly decreases in length to its first length to forcibly compress the body element and restrict outward bulging of the body element.
