Evaluation of SL-7 Scratch Gauge Data.

Abstract

This report assesses the value and application potential of the SL-7 scratch-gauge data base. The principal advantage of the mechanical extreme-stress recorders is large quantities of inexpensive data. Their drawbacks are that contributions from different load sources cannot be separated; and there is no reasonable way to distinquish between hogging and sagging response. However, when the scratch-gauge data and electrical strain-gauge data from a second operational season aboard the McLEAN were correlated, a comparison between the form of the curves showed good agreement. Several statistical models were found to describe the data well enough to be used as a basis for statistical inference beyond the range of measured values. The Type-I Extreme-Value distribution, the Weibull distribution, and a four-parameter distribution proposed by M. K. Ochi satisfactorily represent the data in most cases.
