摘要/Abstract

摘要： 以某法兰式复合材料单杆塔工程为背景,在相同设计条件下设计了插接式复合材料单杆塔,并利用有限元软件ANSYS 对其在三个典型工况下的应力、挠度和结构稳定性进行了计算分析。结果显示插接部位环向应力过大,且为结构的薄弱位置。对插接部位提出的两种补强方案进行了计算分析,结果表明对内插管采用钢内衬补强的效果比较明显。文章最后对插接式单杆塔进行了抗扭设计,提出了胶接和螺栓配合的方式防止扭转。

Abstract: Taking the single tower of a flange type made of composite material as study background, composite single pole of a plug-in type was designed in the same design conditions as the original project, and under three typical load conditions, its stresses, deflections and stability safety factors were simulated and analyzed by FEM(finite element method) software. Results reveal that the hoop stress in the plug-in area is too large and in the weak location of the structure. Two reinforcement programs in the plug-in area were put forward and calculated and results show: for internal intubation, the effect of using steel liners as reinforcement is relatively obvious. Finally, the single pole of plug-in type was designed for anti-torsion, and a methods of using glue and bolts to prevent the pole from torsion was put forward.

Key words: composite pole, plug-in, the finite-element method, contact analysis, factor of safety, deflection
