摘要
针对某矿山用大型挖掘机焊接结构构件的开裂事故,模拟实际工况研究了15MnV钢的动态断裂特性,分析了产生脆性开裂的原因。
In the light of the cracking accidence of the welding structure of a large type excavator used in the mine, this paper studies on the dynamic fractu re characters of 15MnV steel through simulating the actual working condition, an d analyzes on the reasons of the occurrence of the brittle fracture.
