摘要

我们求解了泊松方程，得到了基本函数中自由不对称体旋转矩阵的精确解，该旋转矩阵的角速度矢量位于分离矩阵上。这样，我们就可以直接在实验室系统中讨论杰尼贝可夫螺母的时间演变，因为在实验室系统中可以观测到杰尼贝可夫螺母。旋转矩阵取决于两个参数，这两个参数在物理上被明确解释为解法的频率和阻尼系数。对解法的定性分析表明，它正确地描述了单跳的 Dzhanibekov 效应。

An asymmetrical body: Example of analytical solution for the rotation matrix in elementary functions and Dzhanibekov effect

We solved the Poisson equations, obtaining their exact solution in elementary functions for the rotation matrix of a free asymmetrical body with angular velocity vector lying on separatrices. This allows us to discuss the temporal evolution of Dzhanibekov’s nut directly in the laboratory system, where it is observed. The rotation matrix depends on two parameters with clear physical interpretation as a frequency and a damping factor of the solution. Qualitative analysis of the solution shows that it properly describes a single-jump Dzhanibekov effect.
