| Zusammenfassung: | The invention relates to a vibration isolation device and more specifically the invention relates to a vibration isolation device for an aircraft engine oil tank wherein the isolation device includes means for decreasing the mount stiffness when loads above a threshold load are experienced.
A vibration isolation device is disclosed. More specifically the vibration isolation device of the present invention comprises a fuse for decreasing the mount stiffness when loads above a threshold load value are applied to the device. The fuse for decreasing the mount stiffness comprises a shear pin with shear locations that comprise annular grooves with semielliptical cross sections. |
