摘　　要：为准确模拟塔架与拉线组合结构的空间受力特性,采用ANSYS软件,建立三维空间精细化有限元模型,分析该结构的强度与稳定性,对比该塔架有无拉线这2种情况下结构的静力性能和自振特性。研究结果表明:塔架-拉线组合结构整体表现出侧向有弹簧支座的连续梁的受力特性;拉线使结构的受力分布合理化,提高了结构的承载力和刚度。In order to accurately simulate the space mechanical characteristics of the composite structure of the tower with stay wires,a precise three dimensional space finite element model was established by ANSYS,and the structural strength and stability were analyzed.Meanwhile,the static performance and vibration characteristics of towers with stay wires were compared with towers with none wires.The results show that the mechanical characteristics of the composite structure are similar to continuous beams with lateral bearing spring.The stay wires rationalize the force distribution on structures,and enhance the structural bearing capacity and the structural stiffness.
