抱杆销轴连接节点设计与有限元分析
|
摘要
对抱杆螺栓连接型式进行了改进,提出了销轴连接的方法。采用建筑类钢结构规范,完成了抱杆销轴连接节点的结构设计,并运用ABAQUS软件对节点进行了非线性有限元分析,研究了节点在荷载作用下的应力及变形情况。结果表明,销轴节点在设计荷载工况下具有较大的安全系数和强度储备,能够满足正常使用的要求。
In order to improve the bolted connection of holding pole,the method of pin-connected joint was proposed.According to the code of architectural steel structure,the structural design of pin-connected joint was completed,and the nonlinear finite element analysis of the joint was carried out.The stress and deformation of pin-connected joint under the action of load were studied.The results show that the pin-connected joint has greater safety factor and strength reserve under design load.The bear capacity of the pinconnected joint meets the requirements of normal use.
