叶片脉冲电解加工过程的多场耦合模拟

摘要

Compared with EDM,high frequency pulse electrochemical machining (ECM) have significantly improved in the machining accuracy,quality,stability and efficiency aspects. Based on a 3-D engine blade,for the multiphysics coupling simulation of electric field,flow field and temperature field of high frequency pulse electrochemical machining. Contrast and verification of temperature coupled heat transfer,the derivation shows that the role of maintaining stability in the voltage pulse electrochemical machining process.%与电火花加工相比，高频脉冲电压电解加工在加工精度、质量、稳定性及效率等方面有着明显改善。在建立三维航空叶片电解加工区域的基础上，进行了高频脉冲电压电解加工的电场、流场与温度场的多场耦合仿真，对比验证温度耦合热传递，推导说明在脉冲电压电解加工过程中电导率和气泡维持稳定的作用。
