摘　　要：基于MATLAB软件,利用单纯形法搜索最小误差范数,提出了一种针对粘弹材料的经验松弛函数KohlrauschWilliamWatts(KWW)方程与Maxwell模量转换的计算方法,实现了对粘弹材料的广义Maxwell模型的拟合。并以1050℃的粘弹光纤玻璃为例,给出了一组计算实例。In the paper, based on the MATLAB software, using the simplex search method for searching the minimum error norm, a new computational method for experimental relaxation modulus of viscoelastic materials transited to the generalized Maxwell modulus is developed. The computational method for the Maxwell model parameters was realized. Taking the optic fiber glass of 1050 ℃ as an example, one group of data is provided.
