【摘要】 研究事件空间中单面非Chetaev型非完整系统Nielsen方程的Mei对称性和Mei守恒量.建立系统的运动微分方程,给出系统Mei对称性、弱Mei对称性、强Mei对称性的定义和判据,得到由Mei对称性直接导致的Mei守恒量的存在条件以及Mei守恒量的表达式.举例说明结果的应用.
【Abstract】 Mei symmetry and Mei conserved quantity of Nielsen equations for a nonholonomic system of unilateral non_Chetaev’s type in the event space are studied.The differential equations of motion for the system are established.The definition and the criteria of Mei symmetry,loose Mei symmetry and strict Mei symmetry for the system are respectively given.The existence condition and the expression of Mei conserved quantity deduced directly from Mei symmetry are obtained.An example is given to illustrate the application of the results.
