在軸子(Axion)偵測實驗中，大多數實驗使用的圓柱形共振腔之有效體積會隨著目標 頻率的提升而變小。因此，2020年學界提出了圓錐殼共振腔(Conic-shell Cavity)用以突 破此瓶頸。針對此新型共振腔特殊的幾何結構與高負載調頻需求，本研究致力於開發 一套高精度的頻率調控機構，並在室溫環境下運作驗證了理論設計，分析不同驅動材 料之間的利弊。此外，本研究基於材料特性與量測數據，制定了一套頻率調控策略， 旨在克服因阻力導致的機械卡頓問題，確保系統運作的可靠性，並確立了此機械設計 應用於未來低溫環境的可行性。;In axion detection experiments， the effective volume of conventional cylindrical cav- ities diminishes as the target frequency increases. Consequently， the Conic-shell Cavity was proposed in 2020 to avoid this volumetric limitation. To address the unique geo-metric configuration and high-load tuning requirements of this novel cavity， this thesis develops a high-precision frequency tuning mechanism. We validate the theoretical design through actual operation in a room-temperature environment and analyze the trade-off between different drive materials. Furthermore， based on material properties and measurements， we formulate an optimized frequency tuning strategy to overcome resistance-induced mechanical jamming and ensure reliable operation， establishing the feasibility of the mechanical design for the future cryogenic applications.
