研究非保守非完整系统的Herglotz型Noether定理及其逆定理。首先,将 Herglotz变分原理推广到非保守非完整系统,并基于该原理推导出系统的带乘子型运动微分方程。其次,引入无限小变换,研究Her-glotz作用量的不变性,提出并证明非保守非完整系统的Noether定理。再次,研究了对称性逆问题,给出了Noether逆定理。最后,以受非保守力的Appell-Hamel问题为例,介绍Herglotz型Noether定理的应用。
Herglotz-Type Noether Theorem for Nonconservative Nonholonomic System
The Herglotz-type Noether theorem and its inverse theorem for non-conservative nonholonom-ic systems are studied.Firstly,the Herglotz variational principle is extended to non-conservative non-holonomic systems,and the differential equation of motion with multipliers is derived based on this prin-ciple.Secondly,the infinitesimal transformation is introduced to study the invariance of Lagrange-Her-glotz action,and the Noether theorem for non-conservative nonholonomic systems is proposed and proved.Thirdly,the inverse problem of symmetry is studied and Noether's inverse theorem is given.Finally,taking Appell-Hamel problem subject to non-conservative forces as an example,we introduce the application of Herglotz type Noether theorem.
