| Abstract: | To study the conservation laws of high-order nonholonomic systems in event space. Firstly, this paper presents the universal D'Alembert principle in the event space and lead into Dolaptchiew synchronous variation and asynchronous variation. Secondly, it obtains the conservation laws of nonholonomic systems in the event space, which are based upon the invariance of the principle under the infinitesimal transformations. Finally, gives an example to illustrate the application of the result. 14refs. |
