基于ANSYS的输电线路角钢塔连接节点装置分析
|
摘要
为解决输电线路建设过程中铁塔根开和基础根开不对应造成的改造费用巨大问题,提出一种新型的塔脚板连接节点装置,通过有限元分析,掌握了其受力状态和结构性能。新型连接节点装置加工方便、安装便利,对下部基础不产生任何影响,对上部塔腿的微小改造可产生较大的经济效益。
To solve the problem that the tremendous cost of retrofitting had been made by the dissymmetry of the tower root span and foundation root span in the process of the transmission line construction,we invent the new type of connection node device of the tower foot plank.Through the finite element analysis,we can grasp the stress and structure performance.The new type of connection node device can be made easily and installed simply.There is no influence to the foundation of the bottom,there will be good economic benefits from the tiny remodification to the upper tower legs.
