针对核级管道应力计算中难以求取最优解的问题,本研究将云计算与管道应力分析计算相结合,通过设定限制条件,开发了核级管道预处理方法,提出了云计算预处理管道应力分析流程,同时结合特征分析和数据建模,利用支持向量机建立了应力合格模型以节省计算时间。基于核级管道弹簧支吊架数量最小化和支吊架位置合理性的算例表明,该方法可高效、快速求出给定条件下核级管道应力分析最优解。

In order to solve the problem that it is difficult to obtain the optimal solution in the stress calculation of nuclear pipe,this research combines cloud computing with pipe stress analysis progress,and develops the preprocessing method of nuclear pipe by setting the limiting conditions,the pipe stress analysis flow of cloud computing pre-processing was put forward.Meanwhile,the stress qualification model was established by support vector machine to save computing time based on feature analysis and data modeling.A calculating example of minimizing the number of spring supports and hangers and reasonable positioning of the supports and hangers for nuclear pipe shows that this method can efficiently and rapidly solve the optimal solution of stress analysis for nuclear pipe under given conditions.
