摘　　要：利用有限元分析某型号柴油机裂解加工连杆在拉伸与压缩工况下的结构强度,并对连杆进行静载荷安全系数和疲劳安全系数校核。结果表明:在柴油机额定工况14 MPa的爆发压力下,通过裂解加工技术获得的连杆的疲劳安全系数与塑性安全系数均大于1.5,完全满足柴油机的工作要求。This paper carried out the structured analysis of One type fracture splitting connecting rod by using finite element analysis software.And the safety factor and fatigue safety factor of the connecting rod are checked.The results show that,under the burst pressure of 14MPa in rated diesel engine,both the fatigue safety factor and the plastic safety factor are greater than 1.5.The safety coefficient is high enough,which can meet the working requirements of diesel engine.
