| Abstract: |
| Objective To set up a reasonable captive-duration method to examine helicopter-carrier adapting polytype helicopters. Methods According to the helicopter-carrier忆 s environment feature and the regulations of relative standard, combined with the ability of the existing vibration control instrument, the sine frequency point of polytype helicopters was stacked to a same random spectrum, and a comprehensive vibration spectrum assessment method about broadband random stacking spectrum with sine sweeping frequency was proposed. Results Comprehensive vibration spectrum covered the random vibration environment and the sine vibration environment causing by helicopter, organizing one testing could satisfy captive-durations requirement of all the helicopters. Conclusion The method of comprehensive spectrum resolve the captive-duration of the Helicopter-carrier equipped by different helicopters. |
