摘要
研究二阶非完整力学系统的Lagrange对称性,给出二阶非完整力学系统的Lagrange对称性的定义和判据,并得到二阶非完整力学系统的Lagrange对称性导致守恒量的条件和形式。通过算例说明结果的应用。
This paper studies the Lagrange symmetries and conserved quantities for the second-order nonholonomic mechanical system. The definition and criteria of Lagrange symmetry are given. The conditions under which a Lagrange symmetry can lead to a new conserved quantity are obtained and the form of the new conserved quantity is presented. Finally, the application of the results is illustrated.
