圆锥破碎机关键零部件参数化有限元建模与疲劳寿命分析

o predict the fatigue life of cone crusher's key components rapidly, the paper proposed an analysis method which combined parameterized kinetic modeling and parameterized finite element modeling. Simulated cone crusher kinetic model to get the loading course which be used in the key components' finite element model, analyzed the finite element model for the stress result and displacement result. Meanwhile, made fatigue life analysis in the Fatigue Tool module in ANSYS, based on the stress result and utilized the Miner cumulative fatigue damage principle, obtained cumulative fatigue usage index which indicates the components' fatigue performance.
