| Abstract: | In this paper, the Gauss variational principle for variable-mass mechenical systems in a non-inertial reference fram is established by using the method of adding inertial forces. Several forms of motion equations for variable-mass nonholonomic systems in non-inertial reference fram are obtained. The concept of the generalized non-inertial potential of inertial forces is presented and the simplified forms of the equations are given. |
