Finally , has taken the project of locking the end of the segment mirrors and discussed the project ’ s principle and demonstrate 提出了子鏡末端鎖緊方案,該方案可解決子鏡末端穩(wěn)定性不理想的情況,并詳細(xì)論述了方案原理并進(jìn)行了方案的分析論證。
Sequentially it gives a simple and effective method for accurate phase detection of the segmented mirrors of a huge combined mirror 結(jié)果表明,該方法可有效提取出相位信息,從而為分立表面的大型光學(xué)鏡面各單元的精確定相提供了一種簡單有效的方法。
For the adjustable segment mirror ’ s gesture , using flexible hinge to achieve the rotation in second of the segment mirror is a kind of key technology 子鏡姿態(tài)調(diào)整中,采用柔性鉸鏈實(shí)現(xiàn)子鏡二維轉(zhuǎn)動(dòng)調(diào)整是演示樣機(jī)的關(guān)鍵技術(shù),即通過柔性鉸鏈柔性方向的變形來完成角度調(diào)整。
Firstly , have proved the method ’ s validity by comparing with academic analysis ; then , detailed discusses the effect to the whole system of flexible hinge ’ s distortion while adjusting the segment mirror ’ s gesture 仿真分析結(jié)果與理論計(jì)算結(jié)果相對比證明了引入柔性體仿真結(jié)果的準(zhǔn)確性;同時(shí),詳細(xì)論述了角度調(diào)整過程中柔性鉸鏈變形對整個(gè)系統(tǒng)各部分的影響。
Firstly , the structures analysis of the optical synthetic aperture principle demonstration prototype has been introduced . on the basis of these , has modeled the three dimension modeling of this system , analyzed the force of the segment mirror ’ s rotational mechanism and rigid - flexible coupling dynamics simulation . thirdly , analyzed the key parts of the system by making use of the finite element soft 首先,本文對光學(xué)合成孔徑原理演示樣機(jī)裝調(diào)機(jī)構(gòu)進(jìn)行了結(jié)構(gòu)分析;其次,建立了光學(xué)合成孔徑原理演示樣機(jī)三維模型,并對子鏡二維轉(zhuǎn)動(dòng)機(jī)構(gòu)進(jìn)行了受力分析及剛?cè)狁詈蟿?dòng)力學(xué)仿真;最后,結(jié)合理論分析、動(dòng)力學(xué)仿真及實(shí)驗(yàn)研究,對演示樣機(jī)不足之處設(shè)計(jì)改進(jìn)方案并進(jìn)行仿真分析。
A segmented mirror is an array of smaller mirrors designed to act as segments of a single large curved mirror. The segments can be either spherical or asymmetric (if they are part of a larger parabolic reflectorW.
