Automatic Generation of Random Load Spectrum for Aircraft Fatigue Test on Rear-Body in Combination with Tails

Focusing on the random load spectrum adopted for the aircraft structure fatigue test, model and algorism for computing load values, method for generating random load status sequence and flight sequence, and policy of setting up loading time according to load changing amount of key channel are presented in the paper. Automatic generation of complex random load spectrum and setting of the suitable loading time are established by programming. Automation level of generating random load spectrum, smooth level and loading velocity of test are promoted. It gives the trying to improve the application technique on random load spectrum for fatigue tests.
