The . correctness of composite materials shell design theory in cylinders for compressed natural gas vehicles is tested and verified through experiment 用實驗驗證復(fù)合材料殼體設(shè)計理論在天然氣汽車氣瓶設(shè)計中的正確性。
This method enhances the efficiency of solving but not the accuraty , it especially suits cylinders for compressed natural gas vehicles ' s finite element analysis under axis symmetry loads condition 提高了求解的效率而不影響精度,特別適合天然氣汽車氣瓶在軸對稱載荷作用下的有限元分析。
In the last few years , as people pay great attention to economy , enegy and environment , and as the technology of ngv ( natural gas vehicle ) is developed rapidly , cngv ( compressed natural gas vehicle ) is widely used in city " s traffic 近年來,隨著人們對經(jīng)濟、能源和環(huán)境問題的重視,加快了天然氣汽車技術(shù)的發(fā)展,壓縮天然氣汽車(簡稱為cng汽車)廣泛用于城市交通。
From using electric vehicles in new york city during the 1930s to developing water conservation techniques while keeping the familiar brown package cars clean , as well as operating the world s largest fleet of compressed natural gas vehicles , ups has long practiced environmentally - conscious innovations 從1930年代便開始在紐約市使用電動車, ups在保持棕色快遞車乾凈整潔的同時也注意到節(jié)約用水,并建立了世界上最大的壓縮天然氣cng車隊。
The research work of this article is a part of the " reliability research of cylinders for compressed natural gas vehicles " project which was subsidized by chongqing scientific committee , it aims to research the destructive theory and design theory and method for fiber enlaced composite materials shell , and synthetically use finite element optimal technology to set up composite materials cad system 本文的研究工作是重慶市科委資助項目“天然氣汽車氣瓶可靠性研究”的一部分,旨在研究纖維纏繞復(fù)合材料殼體設(shè)計理論及方法和破壞機理,綜合運用有限元優(yōu)化技術(shù)建立復(fù)合材料殼體cad系統(tǒng)。
