摘要: 本文研究了单面非完整系统相对于非惯性系的Noether定理及逆定理。首先给出系统的d'Alembert-Lagrange原理及非等时变分;其次基于微分变分原理在无限小变换下的不变性质,得到单面非完整系统相对于非惯性系的Noether定理及逆定理;最后举例说明结果的应用。

Abstract: Principle of dr Alembert-Lagrange for a system relative to a non-inertial reference frame and non-isochronal variation is first presented. Noether’s theorem and her inverse theorem for the above system relative to a non-inertial reference frame are then studied,based upon the invariance of the differential variational principle under infinitesimal transformations. An example to illustrate the application of the result is finally given.

Key words: analytical mechanics , unilateral constraint , non-holonomic system , non-inertial refer?ence frame , Noether'S theorem , Noether’s inverse theorem
