摘要 用无网格法研究高层筒体结构的自由振动问题。基于移动最小二乘法和弹性系统Hamil-ton原理,建立了筒体结构自由振动的特征方程,并编制了相应的计算程序。计算结果表明,无网格方法应用于高层筒体结构自由振动的分析可行且有效。 The element-free method (EFM) is used to study the free vibration of the high-rise tube structures. Based on the moving least square method and the Hamilton's principle of elastic system, the eigen-equation for free-vibration tube structure is established, and the corresponding computational programme is prepared. The numerical calculation results show that this method is rational and feasible in solving the free vibration of the high-rise tube structures.
