In chapter 3, the subgrid eddy - viscosity model for large eddy simulation is applied to calculate the three dimensions unsteady periodic turbulent flow in yantan francis turbine. the pulsating characteristics of some main physical parameters in flow field are found. the calculated axial water thrust of hydraulic turbine agrees with the model - test value
第三章採用大渦模擬亞格子渦粘模型,對巖灘混流式水輪機的流場進行三維非定常湍流分析,得到了流場中各物理量的脈動特性,計算出ms的軸向水推力與模型試驗值大小相當;同時論證了對于下機架承重的混流式水輪發電機組可採用其推力軸承負荷作為水電站廠房振動的最大垂直激振荷載。A permanent magnet synchronous motor is selected so that the system could work excellently. multiform measures are taken to weakening the torque ripple, such as adopting stator - flume, choosing right ratio of magnet - width and slot - width, and programming properly. a permanent magnet synchronous motor cad software is worked out for predigesting the design of the motor
力矩脈動是衡量交流伺服系統性能優劣的重要指標,為達到理想的控制效果,系統採用正弦波驅動的稀土永磁同步電動機作為執行元件,電機本體的設計綜合採用定子斜槽、將轉子永磁體連續移位、合理選擇永磁體寬度和齒槽寬度比等方法,基本消除了齒槽轉矩;對于紋波轉矩,系統採用軟體的方式加以削弱和補償。A ppt test set has been made, and a measurement system of ppt ' s electric properties ( voltage and discharge current ), isp and thrust has been established. measurement of electric properties of the ppt and its isp, thrust has been carried out
通過大量的研究工作,製造了脈沖等離子體推力器樣機,設計並建立了地面真空環境下對于樣機的放電參數(電壓、電流變化)以及推力、比沖的測量環境,並對所研製的樣機進行了電參數和比沖及推力的測量。
