Abstract

Load spectrum is important for accelerated reliability test and fatigue life prediction of mechanical structure. To study the load spectrum, load signals of transmission system of closed high-speed press were collected under 20 working conditions. The real load signals that reflect dynamic characteristics of the inertial force and the impact load were obtained after signals pretreatment and characteristics analysis. In addition, the load spectrum was obtained after the load time histories had been processed by means of rain-flow counting method. The testing load spectrum provides the first-hand data for fatigue life prediction, studying fatigue damage and accelerated reliability test of the transmission system.
