摘要
本文应用Jourdain微分变分原理研究了非保守力学系统的守恒定律,给出了受二阶非线性非完整约束的非保守系统的广义Noether等式。
Conservation laws of nonholonomic nonconservative dynamical systems are discussed by using the differential variational Jourdain principle. The generalized Noethex's identities of nonconservative systems which are subjected to second order nonlinear nonholonomic constraints are provided.
