Abstract

This paper represents a new solution to the design problem of integrating sufficient power source, actuator, and controller into a "pill-sized" form of a typical capsule. All components are enclosed in an 11 mm diameter, 36 mm long cylinder weighing 7.26 gs. The actuator was designed so that a battery with a capacity of 35 mAh can theoretically supply sufficient energy for 7 h of operation. The excitation's amplitude, frequency, and duty cycle are remotely controlled by a wireless pulse width modulation signal. All steps of the new system development are fully described, including conceptual and embodiment design, fabrication, experimental setup, and parameter identification. The mathematical model is then experimentally validated and used to analyze the system response, where the bifurcation technique is applied to carry out the coexisting attractions and their basins. Recommendations on design and operational parameters are then provided, considering progression and energy efficiencies. The results provide the feasibility of further studies to realize vibro-impact driven and remote-controlled capsules using wireless control in standard size.

毫米级振动冲击遥控胶囊：设计、建模、实验验证和动态响应

本文提出了一种新的设计解决方案，将足够的电源、致动器和控制器集成到一个 "药丸大小 "的典型胶囊中。所有组件都封装在一个直径 11 毫米、长 36 毫米、重 7.26 克的圆柱体中。致动器的设计使 35 mAh 容量的电池理论上可以为 7 小时的运行提供足够的能量。激励的振幅、频率和占空比由无线脉宽调制信号远程控制。本报告全面介绍了新系统开发的所有步骤，包括概念和实施设计、制造、实验设置和参数确定。然后对数学模型进行实验验证，并用于分析系统响应，其中应用了分岔技术来分析共存的吸引力及其盆地。然后，考虑到进步和能源效率，对设计和运行参数提出了建议。研究结果提供了进一步研究的可行性，以实现在标准尺寸下使用无线控制的振动冲击驱动和遥控胶囊。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
