摘要
本文以斜交坐标系下斜板的微分方程为依据,由B样条的性质构造了一组双5次样条基,以其张量积做位移试函数,用权残法中的最小二乘配点法来分析和计算斜板的弯曲问题。本文方法计算简便,边界条件易于处理,计算精度较高。
In this paper, based on control differential equation of skew plate in skew coordinate, a series of spline cardinal is present by the B-Spline characteristics. Its rronecker product is used as trial function, least square collocation of MWR is suggested to be adopted to make analysis and calculation of bending aspect of skew plate. The method of calculation is simple and direct. Its boundary is easy to handle, precision of calculation is high.
