摘要:
在符拉索夫开口薄壁杆件理论平面假定的基础上,对核筒采用三次B样条有限条方法构造连续化模型,并分别计算其动、势能.针对悬挂部分,分别应用连续梁的三弯矩方程和悬吊体系理论,计算其动、势能.然后,由拉格朗日公式,得到悬挂结构体系的动力方程,并用Wilson-θ法求解.最后,结合算例得到了具有实际意义的结论.
Abstract:
The derivation of both potential and kinetic energy expressions is presented for the suspension structure with story vibration absorption apparatus. With respect to the core tube, based on the plane assumption in the Vlasov theory for thin-walled beams with open cross sections, the spline finite stripe method is employed with the cubic B-spline as the displacement coordinate function. Regarding to the suspension parts, FM method and the suspension system theory are applied, respectively. Afterwards, the Lagrange equation is taken to set up the dynamic equations of the structure. Finally, the Wilson-θ method is used to altain the dynamic responses of the structure under the earthquake actions. Through the numerical example, the practical conclusions are drawn. 
