Abstract

Abstract:

The fatigue tests of full scale No.58 titanium frame were large scale and very complicated. Pre fatigue tests of simple simulative specimens were needed in order to find problems which may exist in the full scale tests. The combined load cases were encountered which were not suited for working of fatigue machine during simplification of simulative specimens which were simplified from the full scale titanium frame. This paper presents a conversion method of an equivalent load which can meet the needs of equivalent fatigue life, and the method has been verified by test results.

Key words: fatigue test, equivalent load, fatigue life
