空间有效载荷产品随机振动再验收试验方法研究与应用
The research and application of the retest for space payload equipment of the acceptance random vibration
【摘要】 从空间有效载荷产品再试验需求出发,为进一步理清空间有效载荷产品随机振动再试验,给出了两种制定随机振动再验收试验技术条件方法,通过实例进行了验证,为随机振动再试验技术条件确定提供了一种较为科学、合理的解决方法。
【Abstract】 Focusing on engineering application, two kinds of approaches are provided for determining random vibration retesting conditions, in order to make clearer space payload equipment random vibration retesting. Finally, its application examples for space payload equipment are given to illustrate the process of the proposed approaches. It provides a logical method for determining random vibration retesting conditions.
