碩士 === 國立清華大學 === 動力機械工程學系 === 99 === Abstract In modern society with fast growing economy, people are more demanding in oral hygiene leading to the research in simulation of reciprocated vibrational cleaning actuators. In this thesis, the primary objective is to study the category based on operational principle, design of magnetic circuits, relevant applications and intellectual properties of voice-coil actuators. Aiming at commercial products for benchmarked test samples, the study of mechanism and driving methods have been conducted with later emphasis on design of new actuators so that bulk volume and input power can be reduced. The new actuator has adopted moving-coil structure to be the target of design and analysis which gives smaller volume, winding turns, and power compared to the commercial one. To simulate the vibrational condition of actuator, this study have experimentally measured and recorded the size, electrical parameters and the polarity of the magnet from the commercial one. Then, appropriate parameters of the actuator can simulate the vibrational conditions of the actuator. After the benchmarked study process, new design has given a novel actuator based on material properties of permanent magnet and geometric dimensions of core with final manufacture, assembly and test of the actuator with appropriate driving situations.
