摘要

在这项工作中，我们提出了一种坐标方法来确定分子体在空间中的位置，该方法不使用欧拉角或汉密尔顿四元数。以路易斯波因索不稳定性为例，验证了所开发的高精度计算算法的能力。还分析了易受磁场影响的分子体暴露在外磁场时这种不稳定性性质的变化。

Angular dynamics of molecular bodies

In this work, we propose a coordinate method for determining the position of molecular bodies in space that does not use either Euler angles or Hamilton quaternions. The capabilities of the developed high-precision computational algorithm are demonstrated using the example of the Louis Poinsot instability. The change in the nature of this instability when a molecular magnetically susceptible body is exposed to an external magnetic field is also analyzed.

期刊介绍： Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics. Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences. Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
