摘要
架空输电线路铁塔结构的稳定性对维持安全稳定供电具有非常关键的作用,因现场测量难度较大,故多对其振动情况进行模拟。由于传统模拟方法考虑因素不全面,导致结果不佳,难以提供有效的参考信息,因此提出基于ANSYS的架空输电线路铁塔结构振动模拟。模拟架空输电线路铁塔结构,计算其结构荷载可靠度,基于ANSYS构建三维模拟风场,模拟现实环境条件。模拟结果表明,门型及八字型结构振动幅度较稳定,八字型结构在强风条件下的振动幅度更小。
The stability of overhead transmission line tower structure plays a key role in maintaining safe and stable power supply.Because of the difficulty of field measurement,its vibration is often simulated.Due to the incomplete considerations of traditional simulation methods,the results are poor and it is difficult to provide valid reference information.Therefore,an ANSYS-based vibration simulation of overhead transmission line tower structure was proposed.The overhead transmission line tower structure was simulated,the structural load reliability was calculated,and a 3D simulated wind field was constructed based on ANSYS to simulate real-world environmental conditions.The simulation results show that the vibration amplitude of the portal and figure eight structures is relatively stable,and the vibration amplitude of the figure eight structure is smaller under strong wind conditions.
