| Abstract: | In this paper,the methods of variation of parameters for salving the Vacco dynamical equations are given.Firstly,the auxiliary equations are established.Secondly,the ordinary integration methods are used to salving the auxiliary equations.Thirdly,the parameters are varied.Finally,considering the restriction of nonholonomic constraints to the initial conditions,the solutions of Vacco dynamical equations are obtained.Internal relations between the solutions of nonholonomic and the solutions of holonomic systems are uncovered by the method. |
