和其他近似数值方法(如弦线法)不同,矩阵算子法建立滑移线场网络的精度和分度(间)角无关,而取决于方阵阶数(级数展开式截留项数)。阶数 N=6,一般可获得五位准确数值;N=6～10,计算工作量增大,精度提高不明显;N 小于6,精度明显下降。本文对矩阵算子法求解精度特点进行了理论分析和计算验证。并在电子计算机上,对四种计算方法——近似公式法,弦线法,曲率半经法和矩阵算子法——的求解精度进行了比较。
Unlike other approximate numerical methods (such as the chord method), the accuracy of the matrix operator-based slip-line network establishment is independent of the index (inter) angle and depends on the number of square matrices (number of series expansion cutoffs) . The order of N = 6, the general can get five accurate numerical; N = 6 ~ 10, the calculation of the workload increases, the accuracy is not obvious; N is less than 6, the accuracy decreased significantly. In this paper, the matrix operator method to solve the accuracy of the characteristics of a theoretical analysis and verification. The computational accuracy of the four computational methods, the approximate formula method, the chord method, the semi-curvature method and the matrix operator method, is compared on an electronic computer.
