36MnVS4和46MnVS5连杆裂解性能差异性研究及质量缺陷分析OA北大核心CSTPCD
Research on Difference of Fracture Splitting Performance and Quality Defect Analysis for 36MnVS4 and 46MnVS5 Connecting Rods
针对高强度的36MnVS4和46MnVS5两种裂解连杆用非调质材料,开展了连杆裂解加工性能的对比分析,探究了影响连杆裂解质量的原因,并对连杆裂解加工的边界作出了优化,分析了连杆结构对裂解加工性能的影响.根据连杆实际裂解加工特性,设置了有限元模拟的边界条件.通过分析裂解槽根部的主应力和塑性应变的分布特征,获得了不同材料连杆的裂纹萌生位置;用ABAQUS和FRANC3D两个有限元软件模拟了连杆裂解的裂纹扩展过程,并进行了对比分析;优化了 36MnVS…查看全部>>
A comparative analysis was conducted on the fracture splitting processing performance of two types of high-strength connecting rods,36MnVS4 and 46MnVS5,which were made from non-quenched and tempered materials.The reasons that affected the quality of connecting rod cracking were explored,and the boundaries for connecting rods cracking processing were optimized.The im-pacts of the connecting rod structures on the fracture-splitting processing performance were …查看全部>>
