Actual load spectrum data treatment system

An actual load spectrum data treatment system is briefly introduced, and several aspects about the actual load spectrum data treatment are discussed in detail. An example that the actual load spectrum data of the motive component on a 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 large samples, it is discovered that the stress amplitude follows semi-normal distribution and the stress mean follows Weibull distribution with three parameters.
