摘要
本文采用哈密顿变分原理和正则变换来推导拉格朗日陀螺的运动微分方程,并对天文地球动力学中的日、月岁差(周期为25800年)和章动(周期为18.6年)进行了简单介绍.研究拉格朗日陀螺的运动对解决更为复杂的力学问题具有参考价值.
In present paper,the differential equations of motion for Lagrangian Gyroscope were derived by Hamilton's variational principle and canonical transforms. The helio-lunar precession with a period of 25800 years and nutation with a period of 18. 4 years were then briefly summarized in the astronomical geo-dynamics. Therefore,the investigations for the motion of Lagrange gyroscope may provide a possible theoretical reference for much more complicated problems in Mechanics.
