摘要
利用叠加模型得出变厚度截面高压弯管应力计算式,通过实例同有限元法结果进行了对比。结果表明,误差在允许范围内,该计算式可供工程设计参考。
Stress calculation equation for section area variation high pressure bend pipe is obtained by overlapped module,and compared with the results by finite element method and the results show that the tolerances is within the allowable range and the equation can be the reference for engineering design.
