摘要/Abstract

摘要： 电解转印加工技术是金属双极板流道的一种成形方法,在电解加工过程中,流道轮廓的变化和成形规律难以监测。运用有限元模拟方法对流道成形规律进行模拟和分析,建立电解转印极间电场数学模型,根据电解加工成形理论,利用APDL语言进行基于时间步长的数值分析,模拟流道的电解转印成形过程,并给出相应的试验验证。仿真和试验加工流道深度相对误差低于18%,宽度相对误差低于6%,二者均能反映电解转印加工成形规律。

Abstract: Electrochemical pattern transfer machining is a kind of methods of channel shaping,in which it’s hard to monitor the change of channel profile and shaping law.In this work,a new approach by employing computer simulation method was applied to simulate the channel forming processing.Mathematical model based on electric field was built and finite element method was selected to analyze and compute the corrosion process of channel by using the time-dependent APDL language based on electrochemical machining shaping theory.The comparison denotes that simulation date deviates from experimental in less than 18% in depth and 6% in width of channel.Accordingly the good agreement between theory and experimental data verified the validation of the computer simulation of the channel machining in Electrochemical Machining (ECM).

Key words: electrochemical pattern transfer, electric field, channel, finite element simulation
