# 基于APDL的酒杯型输电杆塔参数化建模与分析Parametric Modeling and Analysis of Cup Type Transmission Tower Based on APDL

With the increasing of transmission lines voltage grade, the transmission line-towers system needs higher static and dynamic stability. But it is difficult to meet the demands of design for the new transmission line-towers in traditional way. In order to improve the design quality on condition of shortening the design lifecycle, the parametric finite element method is applied to model the overhead transmission tower. The parametric template of each basic structure is created by setting the characteristic parameters in APDL environment. Then tower is completed by assembling the basic structure according to their relationship and constraint. In this paper, the LuZ5 tangent cup type tower of 220 kV Gan-Zhen line in Yunnan province is modeled and analyzed. The results show that the parametric modeling is feasible and effective; it can effectively reflect the mechanical properties of the transmission tower, highly increase the rate of creating and modifying the model, and consequently shorten the designing cycle and improve the efficiency.
