基于热-力耦合的航空发动机叶片堆焊修复数值模拟OA
Numerical Simulation of Aero-engine Blade Surfacing Repair Based on Thermal-Mechanical Coupling
压气机叶片极易出现各类损伤缺陷,因此研究其修复技术有十分重大的意义.利用某有限元软件,使用顺序热-力耦合模型对受损叶片氩弧焊堆焊修复过程进行了数值模拟,同时使用Inconel 718合金进行单道堆焊试验.结果表明,数值仿真结果与试验结果吻合良好,所用有限元模型能有效模拟氩弧焊堆焊修复过程.分析不同堆焊层数、不同堆焊方案下叶片温度场、热变形和残余应力情况,模拟过程中熔池形状与实际熔池形状较为吻合,热源中心温度达到堆焊要求;通过对比不同层数下热变形量…查看全部>>
Compressor blades are very prone to various types of damage defects,so the study of its repair technology is of great significance.The process of repairing damaged blade by argon arc welding was numerically simulated by using the sequential thermo-force coupling model with a finite element software,and the single pass welding experiment was carried out by using Inconel 718 alloy.The results show that the numerical simulation results are in good agreement wit…查看全部>>
