The laser radar sub - system determines the heights of the tsp according to the slant height and the oblique angle measured by the laser range finder and the electronic theodolite simultaneously. by lucubrating the motion law of tsp, we decided to compute decent velocities with least - squares procedure & two ranks curve fitting
地面激光雷達跟蹤測量分系統根據測量到的斜距離和俯仰角確定末敏彈傘彈系統的高度，在深入研究末敏彈穩態掃描過程的運動規律后，通過最小二乘法的二階分段曲線擬合，計算出落速。During its storage, transportation, maintenance and service, the solid rocket motor ( srm ) may encounter many incidents such as being dropped onto the ground while being hoisted up, crashing when vehicle turns over during transportation, being struck heavily in takeoff or landing accident while being carried by airplane, impacting with launch platform or buildings when there is abnormality during launch of multiple - stage rocket. impact of great intensity takes place in such accidents, which will lead to srm ignition or explosion
固體火箭發動機在貯存、運輸、維護及使用過程中可能遇到各種意外機械撞擊激勵，例如:吊裝過程中跌落，運輸過程中因交通事故發生翻覆碰撞，機載固體導彈掛飛時因載機發生起降事故導致高速沖撞，多級火箭發射初期因發射異常與發射架或地面建築物發生碰撞等，固體火箭發動機將受到劇烈機械撞擊載荷作用，導致其著火燃燒甚至爆炸。In this paper, the three level fortification criterion, two stage design method and the elastic response spectrum theory are adopted, and the program of nba ( the program of nonlinear - aseismic analysis for beam bridge ) is used to calculate. through gathering, analyzing and calculating a lot of bridge design materials, this paper induces a simple way to calculate the relative displacement of the beam and the pier, and then according to the current design method, it concludes a better design principle of the supporting length of the beams. at the same time the dynamics is adopted to put forward the design method of the carrying capacity and the lengthen of prestress wire ( steel bar ) falling - off prevention structures of highway bridges
本論文採用三水準設防、兩階段設計方法、彈性反應譜計算理論，運用橋梁結構非線性地震響應分析程序nba （ theprogramofnonlinear ? aseismicanalysisforbeambridge ）進行計算；通過收集大量的實橋設計資料，經分析計算，歸納總結出計算上下部結構相對位移的簡便計算方法；並綜合國內外的經驗值，提出梁的支承長度se的設計原則；同時運用動力學突加荷載的原理，推導分析了預應力鋼絞線式（鋼棒連接式）落梁防止裝置設計承載力的計算方法和設計伸長量s _ f的取值；最後本文通過實橋計算，說明了落梁防止系統設計的方法。Over the years, lrt technology has been upgraded to counter the negative effects of traffic jams, noise, environmental damage, air pollution, etc. featuring a small radius of curvature, multiple car units, modulated train set, enlarged cars both in transverse and longitudinal directions, low car floors, streamlined car design, advanced control systems, and flexible right of way, modern lrt systems have been successfully adopted to most environmental and social needs. they adequately display their merits as transportation systems ; i. e., the lrt system is able to co - exist with automobiles. the low car floor means that roads can act as station facilities, and passengers can get on and off the cars in the street
輕軌運輸系統lrt源起於歐洲街道電車street car ，街道電車一度在都市捷運化與私人機動化的浪潮沖擊下迅速沒落，但隨著都會地區機動車輛不斷增加，道路交通阻塞噪音環境破壞排放廢氣污染問題嚴重惡化之際，輕軌車輛技術已不斷提升，具備小轉彎半徑能力的聯結式車廂模組化列車編組車廂斷面長度加大加長低地板車廂流線型車廂設計，搭配先進控制系統及彈性的路權型式，使現代化輕軌系統具備有與生活空間結合重視環境問題與社會情勢並活用進化街車之都市交通工具等特徵與優點，如高性能輕軌列車與汽車共存，低底盤的車廂創造無障礙車站空間，道路即是車站設備，旅客可以在街區上下車，提供沿線居民高度的便利性，消除交通堵塞噪音及空氣污染等，輕軌系統並與街景充分的調和，成為活動的都市意象。分享友人
