摘要
介绍2000 t港口固定式桅杆起重机臂架的结构类型和构造特点,分析A型双臂臂架结构的受力特点、设计计算方法,阐述格构式圆管结构和实腹式板梁结构的设计差异;分析压弯结构的臂架受压和受弯情况,给出各载荷对臂架整体稳定应力的影响,并说明其占比情况。
In this paper,the structure type and structural characteristics of the 2000-t port fixed mast crane arm shelf is introduced.The force characteristics,design and calculation method of the A-type double-arm shelf structure is analyzed.Besides,the design difference between lattice circular tube structure and solid web plate beam structure is expounded.For the boom of the compression-bending structure,the compression and bending conditions are analyzed,the influence of each load on the overall stable stress of the boom is given,and its proportion is explained.
