Fatigue Life Analysis of Large Linear Vibrating Screen
The crossbeam, side plate and other structural parts of the large linear vibrating screen will be in the multi-axis stress state when the vibrating screen work in the role of harmonic exciting force. So the multi-axis fatigue damage model of the large linear vibrating screen is established and fatigue life is analyzed by using the critical plane method. The logarithm fatigue life nephogram of the vibrating screen is obtain and the fatigue life distribution is analyzed. The results show that the large linear vibrating screen has a high fatigue reliability and the fatigue life can meet the operation requirements. But the local fatigue safety factor of the crossbeam and side plate is low, this should be paid enough attention in the process of design and use. If necessary, the vibrating screen components should be optimized and re-designed.
