旋翼阻尼 的英文怎麼說
中文拼音 [xuányìzǔní]
旋翼阻尼
英文
rotor damping-
Helicopter is hard to hover precisely for its bad stability. ordinarily, it is improved by flight control system, such like rotorcraft unmanned aerial vehicles which use bell bar or bell - hiller stabilizer bar. bell stabilizer bar, fixed across with teetering main rotor, consists of a bar and masses at two ends
貝爾穩定桿由一桿與兩質量塊組成，它與貝爾直升機的蹺蹺板旋翼垂直交叉放置，這種旋翼裝置有助於加大角速度阻尼，改善貝爾直升機的穩定性，但同時也降低了操作性。Model experiment and damping identification for aeroelastic stability of helicopter rotor with elastomeric lag damper
帶粘彈減擺器旋翼系統氣彈穩定性試驗與阻尼識別Later on, the non - linear dynamic model of the coupled rotor - body system with the mrfd was constructed and a test - bed which is fit for this model was designed. at last, the dynamic stability test for the system was implemented. the result of which says that the mrfd can improve the dynamic stability of the system markedly
採用開-關控制策略進行帶磁流變阻尼器的旋翼/機體耦合動穩定性試驗，結果表明，磁流變阻尼器能明顯提高旋翼/機體耦合動穩定性裕度，體現了具有自適應能力的優點。To improve the stability, one common method is to install dampers at the roots of blades. however, commonly used dampers can hardly meet different demands when helicopter working in different conditions
為提高旋翼/機體耦合動穩定性，一般採用在槳葉根部安裝減擺器的方法，但目前常用的減擺器很難滿足直升機不同工作狀態下對擺振器阻尼的不同需求。Therefore, in this thesis, the magneto - rheological damper ( mrfd ) was studied which is of simple structure, high reliability and self adaption
為此，本文研究了結構簡單、可靠性高並具有自適應能力的磁流變減擺器（阻尼器） ，用於控制直升機旋翼/機體耦合動不穩定性運動。Second, taking the characteristics of the mrfd and its matching with blades into consideration, the squeeze mode mrfd was designed. after that, the mechanical characteristics of the squeeze mode mrfd was tested to tell us that, compared with those mrfd work in other modes, the squeeze mode is advantageous for its compact structure, less displacement and higher strength. third, with the test data, we get the force model which use imitatation
其次，考慮磁流變阻尼器自身特點與直升機旋翼的匹配因素，設計了以擠壓模式為工作方式的磁流變減擺器，並對磁流變減擺器進行了力學特性試驗，試驗結果表明擠壓式磁流變阻尼器與其他工作模式的磁流變阻尼器相比具有結構緊湊、位移小、出力大等優點。分享友人
