摘要
进排气边是航空发动机叶片中的重要功能部位,对加工精度有极其严苛的要求.针对某型航空发动机叶片,建立叶片进排气边的阴极三维模型和进排气边电解加工垂直供液的流场模型.采用COMSOL Multiphysics软件模拟进排气边电解加工过程,取不同加工间隙和不同进液口压力为因变量,研究垂直供液电解加工过程中的流场变化规律.实验结果表明,加工时电解液流速与进液口压力呈正相关;在相同电解液压力下,小加工间隙的流场分布比大加工间隙均匀.
Abstract
The leading/trailing edges are important functional parts of aero-engine blades,and have extremely stringent requirements for machining accuracy.In this paper,a three-dimensional cathode model of the leading/trailing edges of an aero-engine blade and a flow field model of vertical liquid supply for electrochemical machining of the leading/trailing edges are established.COMSOL Multiphysics software was used to simulate the electrochemical machining process of leading/trailing edges.Different machining gaps and different inlet pressures were taken as dependent variables to study the flow field variation during vertical liquid supply electrochemical machining.The results show that the electrolyte flow rate is positively correlated with the inlet pressure.Under the same electrolyte pressure,the flow field distribution of small machining gap is more uniform than that of large machining gap.
