Mei symmetry and Mei conserved quantity of Nielsen equation for a nonholonomic system
【摘要】 研究了Chetaev型非完整非保守系统带乘子的Nielsen方程的Mei对称性和Mei守恒量.对Chetaev型非完整非保守系统带乘子的Nielsen方程的运动微分方程、Mei对称性的定义和判据、Mei对称性直接导致的Mei守恒量的条件以及守恒量的形式进行了具体的研究.举例说明结果的应用.
【Abstract】 Mei symmetry and Mei conserved quantity of Nielsen equation with multipliers for a nonholonomic, non-conservative system of Chetaev’s type are studied. The differential equations of motion of Nielsen equation with multipliers for the system,the definition and criterion of Mei symmetry,and the condition and the form of Mei conserved quantity deduced directly by Mei symmetry for the system are obtained. An example is given to illustrate the application of the results.
