摘要
提出了一种研究非完整非保守动力学系统的不变量的方法。首先,将一个非完整非保守动力学系统问题当作一个有条件的完整动力学系统问题来处理;然后建立确定该系统具有形如不变量的方程组,其中a_0,a_s,a_(sl)是t,q_s的任意函数;最后举例说明其应用。
A method of studying invariance of nonholonomic-nonconservative dynamical systems is presented.First,nonholonomic-nonconservative dynamical systems are considered as holonomic dynamical systems with condition,next a set equations of obtaining invariance in the form of I= a0+asqs+(1/2) aslqsql are estabilished,and finally,examples are given to illustrate application of obtained results.
