受定轴转动约束的变质量非完整系统运动微分方程

Differential Equations of Motion for Variable-Mass Nonholonomic Systems with a Fixed-Axis Rotating Constraint

建立了变质量力学系统在定轴转动参考系中的Ｊｏｕｒｄａｉｎ原理，由此得到了受定轴转动约束的变质量力学系统运动微分方程，给出了准坐标形式，最后举例说明方程的应用。

he Jourdain principle in a fixed-axis rotating reference system is established for variablemass mechanical systems.By the principle,differential equations of motion for variable-mass nonholonomic systems constrained to the fixed axis rotation are obtained. The equations in terms of quasi-coordinates are presented.An example is given to demonstrate the application.
