高斯最小拘束原理是力学中一个重要的普遍原理,它给出了质点系的真实运动和可能运动相区别的标志。这一原理也可用于研究刚体系的质心运动规律。本文针对刚体系的转动,提出了转动拘束的概念。对刚体系的真实转动,转动拘束取得极小值。并表明了它与其他力学一般原理的等价性。它对解决刚体系的转动问题是方便的。 The Gaussian minimum restraint principle is an important universal principle in mechanics. It gives the sign of the difference between the real movement and the possible movement of the particle system. This principle can also be used to study the centroid motion of a rigid system. In this paper, the concept of rotational restraint is proposed for the rotation of rigid system. On the real system of rotation, rotation restraint achieved minimum. And shows its equivalence to the general principles of other mechanics. It is convenient to solve the rotation problem of just system.
