摘　　要：本文建立了螺旋管结构动力分析的简化模型，给出了该简化模型的固有动态特性解的半解析数值实现方法。算例表明，该建模是合理的，该数值方法精度良好、占用机时少于有限单元法。计算结果与试验结果符合较好。In this Paper, a simplified model for the dynamic analysis of belieal tube structure isfound. The calculating method which can be used to semi-analytically determine the naturaldynamic properties of this model is given. Exemples show that this model is reasonable, thecalculating method is exact enough and takes less computer time than finite-element method.The evaluated results are in good agreement with expelment results.
