道亨铁塔满应力分析软件与自立式铁塔内力分析软件的对比分析

Comparative Analysis of Daoheng MYL Software and TTA Software

针对GB50545—2010对铁塔设计提出的新优化要求,通过对国内最常用的道亨铁塔满应力分析(MYL)软件与东北电力设计院的自立式铁塔内力分析(translation tower analysis,TTA)软件2种铁塔设计软件进行分析,认为MYL软件建模速度和计算速度快可实时动态显示模型,操作直观,能提高铁塔设计效率。阐述MYL和TTA软件的异同点及相互格式转换的方法;通过计算实例的结果分析,给出杆件使用率相差较大的原因,使设计人员能清晰认识2种软件的差异,并在利用TTA计算文件的基础上,充分发挥MYL软件的优点,快速提高工作效率。

Aiming at new optimization requirements of GB 50545-2010 on tower design and through comparative analysis of the commonest Daoheng MYL software and（Translation Tower Analysis） TTA software of Northeast Electric Power Design Institute,it is believed in the paper that the fast modeling and calculation speed of MYL software enables real-time and dynamic model display,intuitive operation and promotion of tower design.The paper elaborates on similarities and differences as well as conversion method between MYL and TTA.By analyzing result from example calculation,reason for difference of member usage is given so that designers can realize the differences between the two softwares,exert advantages of MYL and promote work efficiency on the basis of using TTA calculation files.
