| 目的 研究舰载机机载装备弹射起飞和拦阻着陆冲击试验的工程实现方法。方法 从GJB 150.18A—2009、MIL-STD-810F/G及其提供的实测数据出发，分析弹射起飞和拦阻着陆冲击载荷特征，对几种常用试验方法的工程实现进行探讨和比较。结果 弹射起飞和拦阻着陆冲击具有瞬态、交变、低频、大位移、高速度等特征。阻尼正弦波方法的实施路径比较明确，复杂波形再现方法实施路径比较模糊且复杂，超长脉冲半正弦波方法具有多种局限性，前两种方法的速度、位移都较大。结论 阻尼正弦波方法较复杂波形再现方法更容易实现，但两者都需要大位移、高速度的专用冲击试验设备和适当的波形处理技术，超长脉冲半正弦波方法在前面两种标准推荐方法能够实现时，不建议使用。 |

| 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. |
