正交实验在压力容器设计中的应用

Orthogonal Experiment in Designing Pressure Vessel

针对承受内压薄壁圆筒的应力问题,以正交实验设计出的实验方案,利用大型有限元软件AN-SYS分析代替实验方法,再用统计方法分析模拟结果,而后比较拟合公式与理论公式,误差在工程允许的范围内。

Considering the stress of pressurized cylinder shell,the ANSYS was employed to analyze orthogonal experiment results,then having it simulated with statistical method and having the fitting formula compared with the theoretical formula so that any error can stay within the range allowed by the engineering.
