摘要

摘要: 构建了一类基于音圈直线电机的振动驱动机械系统，其振动驱动器是一个分段线性系统，整体构成一个非光滑动力系统，根据不同运动状态建立了系统的碰撞振动方程。基于非光滑动力学的理论对系统周期运动与参数间的分布规律进行研究，并分析了系统平均驱动速度与对应系统参数域（电流频率、幅值和质量比）之间的匹配规律。通过数值模拟表明：当系统运动为周期1/1运动，并且具有较大的冲击速度时，系统的平均驱动速度达到最大值。电流幅值对平均驱动速度的大小有较大影响，对频率带分布没有影响；间隙对系统平均驱动速度大小及频率带分布的影响较小；质量比对平均驱动速度的大小及其频率带分布的影响较为显著。

Abstract: A vibration-driver based on voice coil linear motor is designed, and this vibration-driver moves in a single-way direction, is a piecewise linear system and forms a non-smooth dynamic system. Its impact vibration equation is established according to the different state of motion. The periodic motion and the parameter distribution law of the vibration-driver is studied based on the non-smooth dynamics theory. The matching rules between average driving velocity and corresponding parameter domain (current frequency and amplitude, mass ratio) are analyzed. The numerical simulation shows that the average driving velocity of the vibration-driver reaches maximum when the vibration-driver has a 1/1 periodic motion and a large impact velocity. The magnitude of the current has a great influence on the average driving velocity but has no effect on the distribution of frequency band. The effect of the gap on the average driving velocity and the distribution of frequency band is small. The influence of the mass ratio on the average drive velocity and its distribution of frequency band is obvious.
