Crack Formation in Metal Structures of Heavy Dump Trucks during Operation at Kuzbass Open Pit Mines
T.F. Gorbachev Kuzbass State Technical University, 650000, Kemerovo, 28 Vesennya St., the Russian Federation
The results of crack formation monitoring in metal structures of BelAZ heavy dump trucks during their operation at Kuzbass open-casts are given in the article. Possible causes and areas of the crack-like defects formation during operation of heave dump trucks at depths greater than 300 m are considered. The assembly units and elements of heave dump trucks and the areas of the highest total stresses are determined by solid modeling, strength analysis and monitoring of the condition of metal structures under production conditions. The law of crack length development in the areas of the transaxle-housing component and the fastening of the hydraulic cylinder depending on the number of loading cycles is established. The stresses dependence arising in the structural elements of heavy dump trucks during operation under various loads, on the number of loading cycles to failure, is presented.
