摘要針對螺旋槳飛機模型帶動力風洞實驗要求,通過氣動性能分析提出驅動電機的技術指標,在滿足結構約束的條件下,通過合理設計電機的電磁負荷、校核發熱、採用高效冷卻裝置等,研製出短時工作制高功率密度三相異步電機。The propeller may be overloaded which caused by some reasons when ship has been serviced for a period of time. as a result, the rated revolution of the engine cannot be achieved, or the engine may be on overloaded operation condition. it will not be in the optimum matching between the propeller and the engine
船舶在使用過程中,常因各種因素使螺旋槳出現負荷過「重」的現象,主機達不到額定轉速或超負荷運轉,槳機不能處于最佳匹配;另外當船舶人為地降速航行時,主機處在半負荷情況下工作,如果轉速下降太多,使得主機的工作條件變壞,容易引起主機部件的損壞。The thesis basically realizes the engine testbed using fuzzy pid controlling and loading according to the propeller characteristic
本文初步實現了模糊pid控制演算法並應用於發動機臺架試驗和按照螺旋槳特性模擬加載負荷。Presently most of the theoretical method to predict the propeller - induced hull pressure fluctuation is based on the calculation method in which the pressure is induced by pulsating source in infinite flow. the calculation method is adopted and the corresponded computer program is complied. the propeller - induced hull pressure fluctuation due to blade thickness, blade load, cavity thickness and the change of the cavity volume can be analyzed respectively in the computer program
目前,螺旋槳誘導的船體表面脈動壓力的理論預報方法,大多是以無限流場中點脈動源誘導的周圍流場的脈動壓力的計算方法為基礎的,本文採用該方法編制了計算程序,可以分別考慮槳葉厚度、槳葉負荷、槳葉上空泡厚度及其體積變化在船體表面指定位置上產生的脈動壓力。The primary purpose of this paper is how to solve the overloaded propeller ' s condition. the style of propeller trailing edge cutting and shave on the pressure surface is adopted. the propeller ' s actual effect pitch will be reduced which cause the propeller ' s torque down
本文主要是考慮螺旋槳出現負荷過重時如何處理的問題,所以採用槳葉隨邊切割並在葉面處將翼型修順的方式,實質上是切割后導致螺旋槳實效螺距的減小,從而使螺旋槳吸收的轉矩降低來達到主機負荷降低的目的。分享友人
