| Unified Symmetry of Nonholonomic Mechanical Systems of Non-Chetaev‘s Type with Unilateral Constraints | |
| 摘 要： | The definition and the criterion for a unified symmetry of nonholonomic mechanical systems of nonChetaev‘s type with unilateral constraints are presented based on the total time derivative along the trajectory of the system. A new conserved quantity, as well as the Noether conserved quantity and the Hojman conserved quantity,jeduced from the unified symmetry, is obtained. An example is given to illustrate the application of the results. |
