摘要: 本文从变分原理出发,利用[1]的结论;(1)d-δ运算是可交换的;(2)限制虚位移的Appell-Chetaev条件是多余的,导出一类一阶非线性非完整力学系统的不带乘子的Lagrange方程.这种形式的方程是新的.

Abstract: Making use of conclusions from [1]: (1) d-δ operations are commutative; (2) the Appell-Chetaev condition restricting virtual displacements is superfluous, the present paper derives the Lagrange equation without multipliers for a class of first-order nonlinear nonholonomic dynamical systems by means of variational principle. This kind of equations is new.-
