摘要
依据Fl櫣gge壳体理论 ,分析了正交各向异性圆柱壳在轴向压力作用下的稳定和自由振动特性 ,详细讨论了壳体几何参数和材料特性参数以及轴向压力对于自振频率的影响 ,给出了最低频率随L/R变化的包络线。
A study for an orthotropic circular cylindrical shell subjected to axially loaded is present in this paper. For shear diaphragms at both ends, the resulting characteristic equations about pressure and frequency are given. The effect of shell's parameters (L/R, h/R) and material properties on the free vibration characteristics have been studied. Differences between Love-Timoshenko, Donnell equations and that of Flügge theory are examined too.
