本研究針對電子血壓計中微型幫浦馬達所產生之振動問題進行探討。於非侵入式血壓量測系統中，馬達運轉所產生之機械振動可能透過結構傳遞至感測模組，進而影響量測穩定性與準確性。傳統減振材料多採用泡棉或矽膠作為緩衝介面，但其性能受材料特性限制且缺乏幾何可調控能力。因此，本研究提出以三週期極小曲面（Triply Periodic Minimal Surface， TPMS）結構作為減振元件，利用其幾何可設計特性調控力學與振動行為。 本研究建立血壓計幫浦減振系統，選用Schwarz-P TPMS結構，並以單元尺寸、壁厚及預壓縮比作為設計參數，透過Box–Behnken Design（BBD）進行實驗規劃。藉由幾何分析、壓縮試驗、振動量測、模態分析及DOE分析，評估TPMS結構之力學與振動性能，其中力學性能以總吸收能量（E_abs）及比能量吸收（SEA）進行評估；振動性能則以最大加速度（Max G）、頻譜峰值及統計指標進行分析。 實驗結果顯示，TPMS結構之幾何參數對力學與振動性能具有顯著影響。其中，高吸能結構與高減振結構並未呈現一致趨勢，顯示能量吸收能力與振動抑制效果分別對應不同之力學與動態行為機制。模態分析結果顯示，較低自然頻率之結構通常具有較佳之振動隔離能力。DOE分析結果則指出，單元尺寸與預壓縮比為影響振動性能之重要設計因子，並可透過反應曲面法進行最佳化設計。 此外，與傳統泡棉及矽膠材料相比，TPMS結構於振動指標分析中呈現較佳之振動抑制能力。綜合上述結果可知，TPMS結構可透過幾何設計調控其力學與動態特性，並驗證其作為減振元件之可行性，可作為小型機電系統與可攜式醫療設備減振設計之參考依據。;This study investigates the vibration issue induced by the micro-pump motor in electronic blood pressure monitors. In non-invasive blood pressure measurement systems， motor-generated vibrations may be transmitted through structural components to the sensing module， thereby affecting measurement stability and accuracy. Conventional damping materials， such as foam and silicone， are commonly used as cushioning interfaces; however， their performance is limited by material properties and lacks geometric tunability. Therefore， this study proposes the use of Triply Periodic Minimal Surface (TPMS) structures as vibration isolation elements， utilizing their geometrically controllable characteristics to regulate mechanical and dynamic behaviors. A vibration isolation system for a blood pressure monitor pump was established using Schwarz-P TPMS structures. Cell size， wall thickness， and pre-compression ratio were selected as design parameters， and a Box–Behnken Design (BBD) was adopted for experimental planning. Geometric analysis， compression testing， vibration measurement， modal analysis， and Design of Experiments (DOE) were conducted to evaluate the mechanical and vibration performances of the TPMS structures. Mechanical performance was assessed using absorbed energy (E_abs) and specific energy absorption (SEA)， while vibration performance was evaluated through maximum acceleration (Max G)， frequency spectrum peaks， and statistical indicators. The experimental results demonstrated that geometric parameters significantly influenced both mechanical and vibration performances. Structures with superior energy absorption performance did not necessarily exhibit the best vibration isolation capability， indicating that energy absorption and vibration suppression correspond to different mechanical and dynamic mechanisms. Modal analysis revealed that structures with lower natural frequencies generally exhibited better vibration isolation performance. DOE results further indicated that cell size and pre-compression ratio were the primary factors affecting vibration performance， and response surface methodology could be employed to identify optimal design conditions. Furthermore， compared with conventional foam and silicone materials， the TPMS structure exhibited superior vibration suppression performance. The results verify the feasibility of TPMS structures as vibration isolation elements and demonstrate their potential for vibration mitigation applications in compact electromechanical systems and portable medical devices.
