Formulation and Solution for Inverse Problem of Nonholonomic Dynamics

摘要: 本文给出非完整动力学逆问题的一种提法和解法:已知某些积分,来求施加在系统上的非完整约束的形式;进而在已知系统动能表达式的情况下,来求加在系统上的广义约束反力;最后,给出例子说明解法的应用.Abstract: This paper presents a formulation and solution for the inverse problem of nonholonomic dynamics:to find the form of nonholonomic constraints when some integrals are given and to find the generalized reactive forces of constraint acting on the system when the expression of the kinetic energy is given. An example is given to illustrate the application of the result.
