摘要
在GB 150-2011中新增了开孔补强分析法,其理论基于应力分析,而计算步骤却非常简洁。然而,由于有大量算图,难以实现用计算机软件计算。介绍了在SW6—2011过程设备强度计算软件中实现自动计算的过程,重点介绍样条函数曲线回归方法。文章的介绍还将有助于SW6用户调整计算参数,以及验证开孔补强分析法结果的合理性。
In GB 150--2011, a new reinforcement design method, which is based on stress analysis and with quite simple process, is added. However, because large amount of curves has to be used in calculation, it is difficult to realize this method with software. In this article, the method of using spline function to regress these curves were introduced, in this way, this reinforcement calculation will be executed automatically in SW6--2011. What presented herein can be helpful in adjusting parameters when using SW6 and in estimating the correctness of the result from this analytical reinforcement method.
