UG－NASTRAN在大锥角变径段设计中的应用

摘要

The stress analysis using the finite element software design, can make fast and full optimization of designresult . The stress analysis design using UG-NASTRAN,comparing with conventionaldesign methods,The wall thickness of this sec-tion reduced,material and manufacturing costs reduced,but the economy Improved.%利用有限元软件进行应力分析设计，对设计结果进行快速全面优化。使用UG－NASTRAN对大锥角变径段进行应力分析设计，与常规设计方法相比，使得该段壁厚减小，降低了原料和制造成本，提高了经济性。
