Dynamic Modeling of a Hydraulic Excavator Stick by Introducing Multi-Case Synthesized Load Spectrum for Bench Fatigue Test
A multi-case load spectrum compiling method is PVC FREE DRYERBALLS proposed in this study for dynamic modeling of a hydraulic excavator stick to simplify and accelerate the fatigue bench test.This new method includes a simplified criterion of small-load-omitting threshold based on the principle of invariable fatigue damage, an extreme value inferen
