链斗式采金船主桁架的设计要点

The key point of designing main trusses of chain dredge

本文通过对河南寺湾金矿的100升采金船主桁架的分析.阐述了桁架中绞接点、刚结点的构造对结构设计的影响,另外通过斜支撑杆件的布置找出了内力、侧移变形量和水平荷载的关系.

Based on the analysis of the main trusses of 100 litre gold dredge in Si Wan Gold Mine, Henan Province, this paper has described the influence on structure design caused by the hinge point and rigid point in the main trusses. The relationship among internal force, sidesway variable quantity and horizontal load are determined by the arrangement of the sway brace.
