hollow beam

基本解释

The hollow beam construction not only produce the stress concentration, reduce the effect of beam mass but also extended the bandwidth.
采用空心梁结构不仅能产生应力集中而且能减少梁的自身质量带来的影响，可以有效地展宽频带。
The paper introduces the construction technique, construction process and quality control on key tache for the! prestressed hollow beam of Tongmi Bridge.
介绍垌利大桥预应力空心梁的施工工艺、施工程序、重要施工环节的质量控制。
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.
结果表明，驱动桥壳空心梁和半轴套管部分的应力远小于材料的许用应力，而悬架支座与桥壳连接处出现了局部应力过大的情况。
