Optimization design of high speed-self-locking hydraulic brake 高速自鎖緊液壓制動(dòng)器的優(yōu)化設(shè)計(jì)
Uses and traits of three-dimensional gis were fully comprehended and contrasted, and we completed simulation display and real time information search . flow field situation can be seen through flying route and figures from different direction . raising visibility and simulation level is beneficial to promote the advance of navigation lock hydraulics 對(duì)三維gis軟件的功能特點(diǎn)進(jìn)行了充分了解和對(duì)比分析,并首次將三維gis功能用于船閘引航道水流模擬顯示與信息查詢方面,完成了三維仿真顯示,并進(jìn)行實(shí)時(shí)信息查詢,同時(shí)可通過(guò)飛行路線、不同視角來(lái)從各個(gè)角度查看流場(chǎng)情況。
The research contents and advance of ship lock hydraulics were deeply analysised . aiming at defects in display, search and data processing, an application system of gis in ship lock hydraulics that can run independently were developed by components development technique with mapobjects and ado of database on the basis of full apprenhend of advance and use of gis 在充分了解gis發(fā)展動(dòng)態(tài)與gis技術(shù)功能的基礎(chǔ)上,對(duì)船閘水力學(xué)研究?jī)?nèi)容與研究進(jìn)展進(jìn)行了深入分析,針對(duì)現(xiàn)有描述方式在信息顯示、查詢與管理方面的一些不足之處,通過(guò)組件開(kāi)發(fā)技術(shù)與數(shù)據(jù)庫(kù)的ado訪問(wèn)技術(shù),采用gis二次開(kāi)發(fā)功能組件mapobjects,研究開(kāi)發(fā)了獨(dú)立運(yùn)行的船閘水力學(xué)gis應(yīng)用系統(tǒng)。
