Shock and vibration mount

摘要

A machine mount is disclosed. The mount is ideally suited for naval applications but is generally applicable to any type of equipment. The shock and vibration absorbing part of the mount is made of elements of molded urethane or similar material that change shape as static loading increases. The mount has elements shaped to give a smooth but non-linear, increasing response in static loading. As the static load is applied the extra deformation increases the mount stiffness in two ways, there is an increase in load to mount surface contact area and the elements of the mount change from flex loading to shear and compression as the shape of the elements change under load. The natural frequency of the mount in loading is low and relatively constant over a wider range of static loads then prior art mounts. The advantages include a significant increase in shock and vibration performance compared to current mount designs, allowing a significant reduction in the number of different mounts required to cover the large range of system configurations and attendant cost reduction.
