Fatigue Life, Load Spectrum, Optimization, Transmission Shaft, ZL50 LoaderAbstract
The research analyzes the transmission shaft fatigue performance of the ZL50 loader because this essential element endures various dynamic operational loads. The research examines shaft durability through simulation of fluctuating load data while applying Rainflow Counting and Miner’s Rule to study different load magnitude and frequency effects. The accumulation of fatigue damage becomes most prominent when small frequent loads approach 0 N·m simultaneously with rare large ones reaching 1000 N·m. According to the sensitivity analysis the fatigue life of the shaft drops with higher load magnitudes thus showing us the need to maintain precise operational load specifications. The optimization approach determined that lower load intensities together with reduced cycling occurrences improve shaft endurance through fatigue resistance mechanisms. The research demonstrates that improvements in both operational procedures and design specifications allow significant enhancements of ZL50 loader transmission shaft durability and reliability. The research introduces a new strategy for fatigue management and load spectrum control to offer implementable methods which enhance heavy machinery element performance.
