塔式起重机塔身高强度螺栓连接的力学模型及有限元分析

Mechanical model and finite element analysis of mast section connecting bolt with high strength for tower crane

对螺栓的连接特性进行了阐述,详尽分析了塔式起重机标准节高强度螺栓连接的力学状态,并建立了有限元模型,采用数值分析方法,对其连接特性进行了评估,弥补了工程分析不足。

Characteristics of the bolt connections are described,and a detailed analysis of tower crane standard section of high strength bolts connecting the mechanical state in this article.A finite element model is established,which uses the resin analysis to conduct an assessment of its connectivity features and make up for lack of engineering analysis.
