| 中文摘要: |
| 研制了一套适用于某航空机载设备的金属丝网隔振器，包括三个不同型号。通过测试机载设备三个方向的载荷和激励频率，确定了减振器的固有频率和刚度，设计了与机载设备重心参考坐标面非对称的减振器布置形式。减振器的隔振效率为81%。进行了动态特性和耐久性验证试验，结果表明，该套金属丝网隔振器能有效抑制共振峰，具有较好的缓冲和宽频带隔振效果，可以作为航空机载悬置系统的隔振元件。 |

| 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. |
