摘要
用弹性中心法的概念分析带有铰链型膨胀节的立体管系的受力问题，推导弹性复原力的计算公式，讨论管系的强度及变形核算问题。
The elastic center method is employed for statics analysis of a tridimensional piping system with hinged expansion joints,The couple equations about elastic forces have been put forward.The strength and deformation calculations are discussed and demonstrated for an engineering example case.
