叶片电化学加工过程多场耦合仿真
Multi-physics Coupling Simulation of ECM Processes for Compressor Blade
摘要
Abstract
A temperature dependent multi-physics coupling model was developed to predict ECM process and shorten the period for modifying machining parameters.Based on COMSOL multiphysics software,ECM processes for compressor blades were simulated and influences of the applied potential and the inlet mass flow on the normal equilibrium gap were analyzed.The simulation results indicate that with the applied potential increasing,the gap is increasing and the distribution of gap is less and less uniformity.However,with the inlet mass flow increasing,the distribution of gap tends to uni-formity.The ECM experiments were carried out according to a set of simulation parameters.Compari-sons between simulation and experimental results indicate that the errors are small when the blade profile curvature changes slowly and the errors are relatively large,but variation trend of the gap is same when the blade profile curvature changes fast.关键词
