| Abstract: |
| One set of metal wire net isolator was developed and tested for airborne equipment, which included three models. Load and exciting frequency of airborne equipment was checked in three directions. Natural frequency and stiffness of metal wire net isolators was determined. Non-symmetry gravity center arrangement of the metal wire net isolators was designed. Dynamic characteristic and durability test result showed that the wire net isolators can restrain resonance effectively, which have better damping and broadband frequency isolating effects; the isolation efficiency is81%. It was concluded that the wire net isolator can be used as vibration isolator of airborne suspension system. |
