hollow beam

基本解釋

The hollow beam construction not only produce the stress concentration, reduce the effect of beam mass but also extended the bandwidth.
采用空心梁結(jié)構(gòu)不僅能產(chǎn)生應(yīng)力集中而且能減少梁的自身質(zhì)量帶來(lái)的影響，可以有效地展寬頻帶。
The paper introduces the construction technique, construction process and quality control on key tache for the! prestressed hollow beam of Tongmi Bridge.
介紹垌利大橋預(yù)應(yīng)力空心梁的施工工藝、施工程序、重要施工環(huán)節(jié)的質(zhì)量控制。
The results show that stress in hollow beam and semi-shaft bush is much less than permissible stress, while joint of suspension frame and axle housing has too large local stress.
結(jié)果表明，驅(qū)動(dòng)橋殼空心梁和半軸套管部分的應(yīng)力遠(yuǎn)小于材料的許用應(yīng)力，而懸架支座與橋殼連接處出現(xiàn)了局部應(yīng)力過(guò)大的情況。
