Due to the effect of centrifugal force the buckling critical pressure of rotating shells is higher than that of nonrotating shells.
本文推导了转动壳体线性屈曲的有限元公式,并用DMAP语言编制相应的程序修改MSC/NASTRAN的解题步骤考虑离心力完成了分析。
The finite element equations of the traveling wave vibration of rotating shells with the effects of the Coriolis and centrifugal force are established in this paper.
转动壳体由于离心力与哥氏力的影响 ,其振动频率随转速变化 ,并且同一振型对应两个不同频率的前、后行波。
