| 摘 要： | 本文应用诺沃日洛夫的壳体理论,对输送液体的层压复合材料圆柱壳的自由振动进行了分析,在分析中忽略了壳体结构的切向及轴向惯性力的影响,考虑了壳体和液体的相互作用,导出了一般情况下的频率方程。实例中对两端简支双层正交异性材料薄片组成的圆柱壳的固有频率进行了数值计算,得到了一些有价值的结果。

| Abstract: | The free vibration of fluid conveying multilayer elastic cylindrical shell is studied. The equations of motion ars described by Novozhilov's theory of shell and the circumferential and axial inertial forces have been neglected. The fluid is assumed to be incompressible, nonviscous and irrotational. The constitutive equation of the shell is based on the classical theory of multilayer shell and is given as follows: The solutions for the displacements are expressed as: u = Ajexp(and w will have to satisfy specific boundary conditions. Numerical calculation has been done for the free vibration frequencies of a simply supported shell with two orthotropic layers. |
