The equivalent damage calculation formulae of fatigue crack formation and growth are established. In order tocompile the fatigue crack formation and growth accelerated load spectra, the main wave shapes and load sequence of theactual load spectrum are kept constant, and the carrier waves are cut off. And secondary waves are put together into newsecondary waves to shorten the test time according to the equivalent damage calculation formulae respectively. Then bythe fatigue cumulative damage calculation of the fatigue crack formation and growth accelerated load spectra, the onecorresponding to the bigger damage is determined as the fatigue accelerated test load spectrum. Therefore in the test pro-cess, the fatigue accelerated test spectrum may be applied till fatigue failure, the engineering fatigue crack length of full-scale structure need not be inspected, and the fatigue crack formation accelerated load spectrum need not be transferredinto the fatigue crack growth accelerated load spectrum. Finally, it is verified by tests of two kinds of specimens that thedamages of the specimens caused by the accelerated load spectra are near to those by the actual load spectra; namely, thetested life of actual load spectra is similar to that of accelerated load spectra. But the test time of accelerated load spectrais shortened by about three-quarters that of actual load spectra. From these tests, it is also found that the fatigue accelerat-ed test spectrum has an advantage over FALSTAFF spectra.
