Shape Preserving Rational Quartic Spline Interpolation Curve of Minimum Strain Energy
摘要
Abstract
In order to obtain the most fairing shape preserving rational quartic spline interpolation curve,an optimization model is established,with the shape control parameters and the derivative of the interpolation function at the nodes being decision variables,the minimum strain energy of the interpolation curve being the objective function,and the interpolation function for monotony as well as the shape control parameters and the derivative of the node greater than zero being the constraint conditions.The shape preserving rational quartic spline interpolation curve with minimum strain energy is obtained based on the optimization model.The numerical examples are given to show that the new method can obtain fairing interpolation curve.关键词
