缠绕式提升机已广泛地使用木材作为衬垫,但是,木衬在承载中的特性、作用以及如何选择衬垫的结构、尺寸等问题,目前仍然不够清楚。这样就妨障了准确地分析筒壳内部的应力情况。为此,本文在这几方面作了一些探索,提出了木衬的力学模型,并将计算结果与实验结果进行了比较。同时对如何选择衬垫的结构也作了些探讨。 However, the characteristics and functions of the wood lining in the bearing and how to choose the structure and size of the lining are still not clear enough. This obstructs the accurate analysis of the stress inside the shell. To this end, this article made some exploration in these aspects, put forward the mechanical model of wood lining, and compared the calculated results with the experimental results. At the same time how to choose the structure of the liner also made some discussion.
