摘要

针对现有研究加环肋圆柱壳振动特性在边界条件方面的局限性,建立了任意边界条件下环肋圆柱壳的动力学模型。将壳体和环肋看作离散模型单独考虑,采用一种改进的傅里叶级数法研究了环肋圆柱壳的固有振动特性,通过与模态实验进行对比验证了本文方法的准确性。在此基础上分析了边界弹簧刚度对环肋圆柱壳固有频率的影响。
Motivated by the limitation of current studies on the dynamic characteristics of the ring-stiffened cylindrical shell,in this paper, the dynamic model of ring-stiffened cylindrical shell with the arbitrary boundary conditions was constructed. The shell and stiffeners are treated as discrete elements and then free vibration characteristics were analyzed. The accuracy of the present method was validated by comparing with results from modal experiment. In addition, the influences of the spring stiffness on the vibration characteristic of the ring-stiffened cylindrical shell were also studied.
