实测载荷谱数据处理系统

ACTURAL LOAD SPECTRUM DATA TREATMENT SYSTEM

简要介绍了实测载荷谱数据处理系统，较深入地论述了实测载荷谱数据处理的几个重要方面．给出了该系统处理直升机旋翼系统动部件实测载荷谱的实例，通过大子样二维疲劳载荷母体分布参数估计及假设检验，发现载荷幅值服从半正态分布。

The actural load spectrum data treatment system is briefly introduced, and several aspects about the actural load spectrum data treatment are discussed in detail. An example that the actural load spectrum data of the motive component on helicopter is treated by this system is given. After the parameters estimation and the assumption test of the two dimensional fatigue load population distribution on the basis of the large samples, it is discovered that the stress amplitude follows semi normal distribution and the stress mean follows Weibull distribution with three parameters.
