摘要

研究了一个刚体在自由分子流中定点运动的问题。证明了该物体的运动方程推广了具有不动点的重刚体的经典欧拉-泊松运动方程,并以质点流中物体表面为球面时的经典欧拉-泊松方程的形式表示。讨论了所考虑的系统中第一积分的存在性。

On the Motion of a Rigid Body with a Fixed Point in a Flow of Particles

The problem of motion of a rigid body with a fixed point in a free molecular flow of particles is considered. It is shown that the equations of motion of this body generalize the classical Euler–Poisson equations of motion of a heavy rigid body with a fixed point, and they are represented in the form of the classical Euler–Poisson equations in the case when the surface of the body in a flow of particles is a sphere. The existence of first integrals in the considered system is discussed.
