飞行器拦阻着陆冲击试验分析

Analysis of Shock Test for Aircraft Arrested Landing

分析了飞行器拦阻着陆冲击环境的特征及其环境效应和拦阻着陆冲击与正常着陆冲击的区别,并根据基本设计冲击和拦阻着陆冲击的加速度响应特性,指出基本设计冲击不能充分覆盖拦阻着陆冲击,最后分析了机载设备经随机振动试验或基本设计冲击试验后免去拦阻冲击试验的条件和分析方法。

The shock environmental characteristic and environmental effect of aircraft arrested landing was analyzed.The difference between arrested landing and normal landing was also analyzed.Based on analysis of the acceleration response of basic design shock and arrested landing shock,it was concluded that basic design shock cant’ fully replace arrested landing shock.The condition and analysis method of relieving of arrested landing shock test via random vibration test or basic design shock test were put forward.
