| Abstract: |
| The paper aims to study the engineering implementation methods for catapult launch and arrested landing shock tests of materiel mounted in or on carrier-based aircraft. Based on GJB 150.18A—2009, MIL-STD-810F/G and the presented measured data, the characteristics of catapult launch and arrested landing shock were analyzed and the present test methods were discussed and compared. The catapult launch and arrested landing shock loads were transient, alternate, in low-frequency, of large displacement and high velocity. The implementation approach of the damped sine wave method was relatively clear; while the complex wave form control method was unclear and complicated. And there were several disadvantages in the super-long-duration half-sine wave method. The velocity and displacement were relatively large in the damped sine wave method and the complex wave form control method.The damped sine wave method is more convenient to be implemented than the complex wave form control method; and for the both methods, special large-displacement and high-velocity shock machines and appropriate waveform processing techniques are necessary; the super-long-duration half-sine wave method should not be recommended when one of the above two standard-recommended methods is available. |
