摘要
应用Kuzmak-Luke的多尺度法求得长度慢变的单摆的渐近解,并与KBM法、椭圆KB法的结果进行比较.数值算例表明Kuzmak-Luke的多尺度法比KBM法、椭圆KB法更精确.
The multiple scales method of Kuzmak-Luke was used to obtain the asymptotic solutions of pendulum with slowly varying length, and the solutions were compared with the results of KBM and elliptic KB methods. The comparison showed that the result of the present method was more accurate than that of KBM and elliptic KB methods, although they were all effective to such problem.
