一类特殊非完整力学系统的辛算法计算

A special nonholonomic mechanical system calculated by symplectic method

对一类特殊的非完整力学系统的动力学性质进行数值研究,采用当前比较优越的保结构算法进行数值计算,并和传统的Runge-Kutta方法进行比较.通过计算结果的比较而得出辛算法在这类特殊的非完整力学系统的数值计算中的优越性.

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.
