Abstract

The parameters of fracture splitting groove have direct influence on the stress-strain field of crack tip. This paper modeled on some cylinder engine crankshaft bearing bracket. Based upon normal stress criterion of cleavage fracture and the mechanics of fracture software ABAQUS, the stress-strain field of different parameters were simulated and analysed, and the effect of parameters on cracking process were investigated using cleavage fracture criterion. The results indicated that the material of crankcase is fragile material. Although the material is not sensitive to gap, but on account of crack initiation, crack growth, machining of fracture splitting groove and fracture splitting load, optimum parameters for fracture splitting groove were selected. The experiment with optimized parameters made excellent results.
