摘要
依据数学规划理论,构造一种以线性包容评定模型的迭代运算去逼近非线性的精确包容评定模型优化解的球度误差评定算法,并建立了适用计算判别的球度误差包容评定最优条件判别准则。算法具有评定精度高、收敛速度快。
This paper is concerned with the nonlinear programming algorithm for evaluating the sphericity error with minimum radial separation sphere center, minimum circumscribed sphere center and maximum inscribed sphere center. The key of the algorithm is to approach optimization of the precise nonlinear programming model by means of the iterative calculation of the approbatory linear programmig model. The algebraic criterion is derived from the necessary conditions of optimization of the nonlinear programming model.
