BSWI Rayleigh-Timoshenko shaft element considering shear deformation is constructed.
构造考虑剪切变形的Rayleigh-Timo-shenko区间B样条小波转轴单元,该单元每个节点具有4个自由度,即:2个平动和2个转动,分别表示横向弯曲和转动位移。
Galerkin method is used to establish the formulas of a high accuraterotor element,in which the effects of shear deformation,rotary inertia ,axial load,gyroscopic mo-ments,internal and external damping are included.
