本文阐述了振动时间—温度谱的统计计算方法和实施情况。 飞机结构和机载设备的高、低、室温正弦扫频振动时间谱,是运用“状态归纳法”对战斗机在使用寿命期内的训练使用和战斗使用进行编谱的一种方法。该法考虑了飞行大纲中全部飞行状态,如实地反映了战斗机的实际使用情况。 按照上述时间—温度谱编制的正弦扫频振动试验大纲,在实验室里对飞机试件进行试验,在实践中证明了它的可行性。
This article describes the statistical method and implementation of the vibration time-temperature spectrum. The high, low, and room temperature sinusoidal sweep vibration time profiles of aircraft structures and airborne equipment are a method of using “state induction” to train the use of fighter jets over their useful lives and the use of combat. The Act takes into account all the flight conditions in the flight outline and faithfully reflects the actual usage of the fighter aircraft. In accordance with the time-temperature spectrum prepared sine sweep vibration test program in the laboratory test aircraft samples, in practice proved its feasibility.
