A special nonholonomic mechanical system calculated by symplectic method
一类特殊非完整力学系统的辛算法计算

This paper studies numerically a special nonholonomic mechanical system. A better algorithm of structure-preserving is adopted to calculate numerically and compare it to the classical R-K method. By comparing the results of two methods, the advantage of symplectic method used on this special nonholonomic mechanical system is presented.
