摘要
用无网格法研究圆柱壳的自由振动问题。从移动最小二乘法和弹性系统Hamilton原理出发,建立了圆柱壳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,该方法在解决壳体结构动力问题中是可行的。
The element-free method(EFM) is used to study the free vibration of cylindrical shell structures.Based on the moving least square method and Hamilton's principle of elastic system,the corresponding eigen-equation is obtained,and the computational programme is written.The numerical calculation results show that this method is reasonable and feasible in solving the dynamic structure problem of the cylindrical shell.
