PREDICTION OF FLAT RING FATIGUE LIFE OF SCRAPER CHAIN BASED ON TEST DATA
In order to prevent the failure of chain flat ring fatigue failure of scraper conveyor chain, the paper based on the field test data to predict the fatigue life of the chain. Taking the 38 × 137 mmC grade chain as the research object, firstly, the tension of the flat ring is monitored on-line during...

| description | In order to prevent the failure of chain flat ring fatigue failure of scraper conveyor chain, the paper based on the field test data to predict the fatigue life of the chain. Taking the 38 × 137 mmC grade chain as the research object, firstly, the tension of the flat ring is monitored on-line during the operation of the scraper conveyor, and the two straight edges of the same flat ring are obviously unequal. The tension load spectrum as the simulation load data;Then, the finite element software is used to analyze the unequal load on the two right angles of the chain flat ring. The stress and strain results are obtained, and the weak key points are found.Finally, based on the results of static strength analysis, the fatigue load of flat ring was simulated by ANSYS nCode DesignLife.The simulation results show that the fatigue life of the flat ring of the scraper conveyor is 30750 cycles, and the chain link is 61500 times.The life conclusion can provide important reference for the later maintenance, replacement and structural optimization of the scraper chain. |
