Structure Design of Knuckle Telescopic Boom Crane Based on Finite Element Analysis

为了设计一种适用于船舶甲板空间有限的吊机,指导折臂伸缩吊机机械结构设计,在介绍机械结构整体设计方案的基础上,基于ANSYS软件建立结构的有限元仿真模型,介绍模型的网格划分、约束建立以及载荷加载方法,研究分析结构的应力和应变。结果表明,所设计的折臂伸缩吊机械结构可满足相应作业需求,并形成了一整套利用有限元手段进行船用折臂伸缩吊结构强度计算的方法。研究结果可为同类船用折臂伸缩吊机械结构的设计和优化提供参考。

In order to design a crane which adapt to the limited ship deck space and guide the mechanical structure design of knuckle telescopic boom cranes,based on the introduction of the overall design scheme of the mechanical structure,a finite element simulation model of the structure is established by ANSYS software.The mesh division,constraint establishment,and load loading methods of the model are introduced,and the stress and strain of the structure are studied and analyzed.The results indicate that the designed knuckle telescopic boom crane mechanical structure can meet the corresponding operational requirements,and a complete set of methods for calculating the strength of marine knuckle telescopic boom crane structure by finite element methods has been formed.The research results can provide reference for the design and optimization of the mechanical structure of similar marine knuckle telescopic boom cranes.
