摘要
本文讨论有关约束分类的几个问题,区分约束的运动学意义及动力学意义的必要性,约束的稳定性与系统变换方程及系统的虚位移的关系等。
This paper discusses some problems about distinguish of constraints: thenecessity of distincting kinematic and dynamic senses of constraints, the relationsbetween the stability of constraints and transformation equations, the virtualdisplacements and the real displacements of a mechanical system, and so on.
