摘要：A shock and acoustic mount for reducing transmission of forces between two relatively moveable members such as a mounted component and a supporting structure, providing a compressible fluid spring with large allowable relative movement of the mounted component and support structure. The mount comprises a casing, a piston shell with one end disposed in the casing and another end extending outside of the casing, and a piston housed in the piston shell, all relatively moveable in response to external axial forces. In one embodiment, the mount is filled with a compressible fluid, such as air, providing an air spring. The piston is sealingly bonded to the inner surface of the piston shell, the bond accommodating acoustic and vibration forces by deformation of the bond material. An annular seal between the piston shell and the casing accommodates large and shock forces. In another embodiment, passive damping is provided and a substantially incompressible second fluid is added to the casing, and there is one air spring inside the piston shell. In a third embodiment, an additional air spring is added outside the piston shell, and the response characteristics depend on the type of force applied to the mount.
