| 摘 要： | 在本文中,作者推导出一种平面问题的具有中间节线的高阶有限条法。该有限条法由于其位移函数是用正弦级数与多项式迭加而成,两端部的位移呈抛物线,故该有限条法能与有限元法混合使用解决复杂结构的分析计算,从而达到比单独使用有限元法降低计算费用、减少输入数据。 |
| 关 键 词： | 高阶有限条法 正弦级数 抛物线 |

| Abstract: | In present paper,the author develops a high order finite strip me-thod for plane problems. Its displacement functions are those that areiterated by sine series and polynomial. The displacement functions attwo ends of strip are parabolas, so this makes it possible to solve co-mplicated structural analysis computing by mixing this finite strip me-thod with fiuile element method. Comparing with the finite elementmethod, this finite strip method can cut down computing costs and de-crease input data. |
| Keywords: | high order finite strip method sine series parabolas |
