| Abstract: | Firstly,this paper presents the principle of D'Alembert-Lagrange in event space.Secondly,it obtains the conservation laws of nonholonomic systems of variable mass in event space,which are based upon the invariance of the differential variational principle under the infinitesimal transformations of group.Finally,it gives an example to illustrate the application of the result. |
