标题： Experimental Observation of Temporally-Evolving Stochastic Vibration Patterns in a Vibrating Motor

摘要： 本文介绍了硬币振动马达随时间变化的随机振动模式的观测结果。 对硬币振动马达施加不同的电压，并使用加速度计记录产生的振动。 尽管随着驱动电压的增加观察到平均振动幅度的整体上升趋势，但瞬时波形表现出明显的非线性和准周期性振幅调制、频率偏移以及随机偏差，在较高电压下这些现象更加显著。 涉及对电机和传播介质进行周期性按压的额外实验揭示了非线性机电响应对初始条件的依赖性。 这些结果表明，硬币型马达的动态行为由电流和位移的复杂非线性关系所主导，这对微型执行器应用中的精确控制具有重要意义。 显示英文摘要

摘要： This paper presents the observations of temporally evolving stochastic vibration patterns of a coin vibrating motor. Various voltages are applied to the coin vibrating motor, and the resulting vibrations are recorded using an accelerometer. Although an overall upward trend in mean vibration amplitude is observed with increasing drive voltage, instantaneous waveforms displayed pronounced nonlinear and quasiperiodic amplitude modulations, frequency shifts, and stochastic deviations that intensified at higher voltages. Additional experiments involving periodic pressing of the motor and the propagating medium revealed the dependence of nonlinear electromechanical responses on the initial conditions. These results demonstrate that the dynamic behaviour of the coin-type motor is governed by a complex nonlinear dependence on current and displacement, with significant implications for precision control in miniature actuator applications.
