摘要
针对重冰气象区220kV耐张大转角铁塔设计,利用有限元分析软件ANSYS对耐张转角铁塔建立了刚架模型和桁梁混合模型,以两种模型的各运行工况作静强度分析、模态分析、地震响应分析和屈曲分析,经过比较和改进,提出优化方案。
In view of the 220kV type ＂T ＂angle tower design for heavy ice-coating area, using finite element analysis software ANSYS, the rigid frame modeling and trussed beam modeling for angle tensoin tower are established. Basing on two calculation modelings, static strength analysis, modeling status analysis, bending analysis and seismic influence analysis under various operating conditions have been done. With comparison and improvement, an optimized scheme is obtained.
