【摘要】 本文推导了两端受扭转弹簧约束的简支输流管道在其支承简谐运动激励下的运动微分方程，并利用Ｇａｌｅｒｋｉｎ方法对其进行了离散化处理。另外，针对于扭转弹簧刚度的两种极限情形①Ｋ１＝０， Ｋ２＝０（两端简支）和②Ｋ１→∞，ＫＺ→∞、（两端固定）进行了讨论，还将运动方程进行了简化。更多还原

【Abstract】 The nonlinear equations of motion of simple - supported pipline conveying fluid with torque springs at both ends, excited by the simple periodic motion of its supporting base in the direction of being normal to the pipeline span, were derived. And the epuations were simplified for two special cases; ①K1 = 0, K2 =0 (simple- supported pipe) and②K1→∞, K2→∞ (clamped-clamped pipe).更多还原
