| Abstract: | Tke m-order relative velocity space is established and the Lagrange function of variable mass system in noninertial reference frame is constructed, and the universal D'Alembert-Lagrange principles of variable mass higher-order nonlinear nonholonomic nonpotential system in noninertial reference frame are obtained; then, the generalized Noether theorem of variable mass higher-order nonlinear nonholonomic nonpotential-systems in general noninertial reference frame is derived, it's conservation laws is studied. All Noether theorems in inertial reference frames and constant mass systems are special cases of the generalized Noether theorem. |
