本文介绍了在一定设计条件下,对焊法兰的优化方法,并对这些方法作出了分析和评估,借助于满应力优化设计方法思路,基于大量对焊法兰设计经验,作者提出了一种方便而又规范的对焊法兰优化设计方法——按比例调整优化设计法。同时,较为详尽地介绍了这一方法的应用,并提供了这一方法与满应力优化设计法相比较的计算结果。 In this paper, the optimization methods of butt welded flange under certain design conditions are introduced and the methods are analyzed and evaluated. With the help of the ideas of full stress optimized design method, based on a large number of design experiences of butt welded flanges, the author presents a Convenient and standardized optimization of welding flange design method - the proportion of optimal design method. At the same time, the application of this method is introduced in detail, and the comparison between this method and the method of full stress optimization design is provided.
