摘要
从研究柔性滚动轴承的动力学模型入手，用Ｌａｇｒａｎｇｅ方程建立了柔性滚动轴承的运行方程，通过求解该运行方程的特征值问题，得出了柔性滚动轴承的各阶固有频率，并用算例表明了本文所提出的方法的有效性，为进一步研究谐波传动的整体动态性能奠定了基础．
Starting from finding a dynamic model of flexible rolling bearing,this paper de- rives the differential equation of motion of flexible rolling bearing by means of Lagrangian equation and discusses its eigenvalue problem for obtaining natural frcquen- cics of various orders.The calculation example shows that the method presented here iS an effective one. So it settles a foundation for further researching dynamic behaviours of harmonic drives.
