Abstract
A vibration isolation device comprising a housing with a housing wall that defines a housing chamber, a first spring pack, a second spring pack, and a surface effect damper located between the first and second spring packs. The first and second spring packs and damper being located in the housing chamber. The isolation device further comprises a fuse mechanism which causes the device to act as a hard mount before the fuse is actuated and as a soft mount after the fuse is actuated.
Claims19
A vibration isolation device comprising a housing with a housing wall that defines a housing chamber, a first spring pack, a second spring pack, and a movable damper located between the first and second spring packs, the first and second spring packs and the damper being located in the housing chamber, the vibration isolation device having a first stiffness when the isolation device experiences vibratory loads below a predetermined threshold load and the vibration isolation device having a second stiffness when the isolation device experiences vibratory loads above the predetermined threshold load, the second stiffness having a magnitude that is less than the magnitude of the first stiffness.
A vibration isolation device comprising a housing with a housing wall that defines a housing chamber, a first spring pack, a second spring pack, and a damper located between the first and second spring packs, the first and second spring packs and the damper being located in the housing chamber, the isolation device further comprising a stiffness switching mechanism which causes the device to act as a hard mount before the mechanism is actuated and as a soft mount after the mechanism is actuated.
