| 摘 要： | 本文把样条子域法应用到折板结构振动分析中,采用三次B样条函数与满足边界条件级数的乘积作为折板的位移函数,应用Hamilton原理建立了折板结构振动分析的样条子域法。与通用有限元法及有限条法相比,本文方法具有精度高,未知量少,程序易于编制等优点。

| Abstract: | In this paper the spline subdomain method is applied to the vibration analysis of the folded plate structures. The cubic B-spline function and series which satisfy the boundary conditions are used for the approximate displacement functions of the folded plate structures.Applying the principle of Hamilton, the spline subdomain method of the vibration analysis of the folded plate structures are derived.In comparison with the ordinary finie element method ov finite strip method, the main features of the presented method are of higher accuracy less unknown coefficients, easily programming, etc. The numerical result shows that the presented method is quite effective. |
