鉴于射流偏转板伺服阀在阀类产品相较下的优点以及国内其成品缺乏的现状,提出了其关键结构放大级的优化设计。运用CAD软件对射流偏转板伺服阀放大级流场进行建模,并对其需要设计的尺寸进行多组建模,再运用CFD软件对上一步的模型进行适当的网格划分和流场分析,得到不同尺寸条件以及不同运动情况下的流体压力、速度分布情况。最后将得到的数据进行曲面拟合,并根据分析结果选取良好的工况点,实现参数的优化。
鑒于射流偏轉闆伺服閥在閥類產品相較下的優點以及國內其成品缺乏的現狀,提齣瞭其關鍵結構放大級的優化設計。運用CAD軟件對射流偏轉闆伺服閥放大級流場進行建模,併對其需要設計的呎吋進行多組建模,再運用CFD軟件對上一步的模型進行適噹的網格劃分和流場分析,得到不同呎吋條件以及不同運動情況下的流體壓力、速度分佈情況。最後將得到的數據進行麯麵擬閤,併根據分析結果選取良好的工況點,實現參數的優化。

In view of the excellent features of the jet deflector servo valve with comparison of other valve products but lack of its domestic refined,the optimal design of its key structure,amplification stage,is proposed.The CAD software is used to make model for the amplification stage flow field of the jet deflector servo valve,and sev-eral models are made for the structure size which need to be designed.Then these models are properly divided into mesh in order to analyze its flow field so that we can get the distribution condition of the flow pressure and velocity on different structure size and moving situation.At last through analyzing the experiment data and surface fitting, the analyzing result and working surface could be used to guide the parameter selection by selecting good working point,namely the parameter optimization.
