The invention provides a vibration test-based airborne suspension reliability test adaptability determination method. The method comprises the following steps of: determining vibration stress V1 and duration T1 at a weak position in a hanging vibration test process of an airborne suspension, and vibration stress V2 and duration T2 at the weak position in the hanging reliability test of the airborne suspension; determining a frequency band F1 with the minimum margin in which the vibration stress V1 covers the vibration stress V2; performing vibration equivalence on the vibration stress V1 and the duration T1 in the frequency band F1 to obtain TY1; performing vibration equivalence on the vibration stress V2 and the duration T2 in the frequency band F1 to obtain TY2; if TY1 is not smaller than TY2, it is predicted that the airborne suspender can meet the requirement of the hang-off reliability test after passing through the hang-off vibration test. According to the method, the adaptability of the reliability test of the airborne suspension object can be analyzed and determined by comparing the vibration stress of the typical frequency band according to the structure weak position on the airborne suspension object in the vibration test and the reliability test of the airborne suspension object.

    本发明提供一种基于振动试验的机载悬挂物可靠性试验的适应性确定方法,该方法为:确定机载悬挂物挂飞振动试验过程中薄弱位置处的振动应力V1和持续时间T1,和机载悬挂物挂飞可靠性试验中薄弱位置处的振动应力V2和持续时间T2;确定振动应力V1覆盖振动应力V2的裕度最小的频段F1;在频段F1内将振动应力V1和持续时间T1进行振动等效,得到TY1;在频段F1内将振动应力V2和持续时间T2进行振动等效,得到TY2;若TY1不小于TY2,则预计机载悬挂物通过挂飞振动试验后可满足挂飞可靠性试验要求。本发明能够根据机载悬挂物振动试验和可靠性试验中的机载悬挂物上结构薄弱位置,通过对比典型频段的振动应力,分析确定机载悬挂物的可靠性试验的适应性。
