Abstract

In this paper, a micro electromagnetic harmonic drive system is proposed. Considering Van der Waals force, dynamics equation of the flexible ring for the micro drive system is deduced and resolved. Using the equations, the effects of the molecule force on the natural frequencies and vibration modes of the drive system are investigated. Results show that considering molecule force, natural frequencies of the flexible ring are reduced and its vibration modes are changed. For lower order modes, smaller clearance between the flexible ring and stator, smaller thickness of the flexible ring and larger radius of the flexible ring, the effects of the molecule force on the natural frequencies and vibration modes are more obvious.

分子力对微电磁谐波驱动系统自由振动的影响

本文提出了一种微电磁谐波驱动系统。考虑范德华力，推导并求解了微传动系统柔性环的动力学方程。利用这些方程，研究了分子力对驱动系统固有频率和振型的影响。结果表明，考虑分子力的影响，柔性环的固有频率降低，振动模态发生改变。对于低阶模态，当柔环与定子间隙较小、柔环厚度较小、柔环半径较大时，分子力对固有频率和振型的影响更为明显。
