For the case, we put forward the methods for decreasing vibration at the peak speeds and study the influence of support plan for vibrational character of rotor - support system of the aeroengine
研究降低峰值轉速下振動水平的方法及支承方案對發動機轉子?支承系統振動特性的影響，得出了有工程參考價值的結論。 -
In sensored case, the theory of hall signal checking ahd how to change phase are discussed. in sensorless design, using a single line resistance measure phase current and estimating rotor position are brought forward by analyse associate codes. at the same time, problems and solution which meet in task are mentioned in report
在有位置傳感器方案設計過程中，詳細討論了霍爾位置信號檢測原理和換相控制原理以及實現過程；在無位置傳感器方案設計中，提出了單電阻電流檢測原理和位置估算的演算法，並且對相關的軟體代碼進行了分析。 -
Abstract : in order to improve the performance of a vortex classifier, a certain type of narrow plates are fitted in the passages between the blades in the rotor cage. this measure results in reduction in the cut size and increase in classifying precision. more significant effect is observed in the case of the rotor cage with fewer blades originally fitted. it is pointed out that the reason is due to the decrease in inertia counter vorticity
文摘:在渦流分級機轉籠通道中心加裝窄葉片使產品分割粒徑減小，分級精度提高.轉籠徑向葉數較少時加裝效果明顯，徑向葉片數多時效果不明顯.分析指出，這是減小了轉籠徑向葉片間慣性反旋渦強度的緣故 -
The theoretical deduction in chapter 3 shows that the shape of load distribution used in the arithmetic is a decisive fact of the error margin size, the more the adoptive shape looks like the actual case, the smaller the error margin will be, therefore the tilt parabola shape can instead of the actual shape of load distribution in the permissible error margin when we predicting constant loading noise caused by the tail rotor of helicopter
在第三章中通過理論推導和計算比較發現，在預測直升機尾槳定常載荷噪聲時，其誤差大小取決于演算法中槳葉弦向載荷分佈的數學描述與實際弦向載荷分佈的吻合程度，而選取一種與實際弦向載荷分佈較為相似的斜拋物線形來預測噪聲所導致的誤差是很小的。
