摘要
本文首先将Gibbs-Appell方程推广到最一般的变质量非完整系统.得到变质量非线性非完整系统在广义坐标、准坐标下的Gibbs-Appell方程和积分变分原理,最后给出一个例子.
In this paper, the Gibbs-Appell's equations of motion are extended to the most general variable mass nonholonomic mechanical systems. Then the Gibbs-Appell's equations of motion in terms of generalized coordinates or quasi-coordinates and an integral variational principle of variable mass nonlinear nonholonomic mechanical systems are obtained. Finally, an example is given.
