本文旨在解決高頻超音波機械掃描式馬達於臨床生物掃描時會因探頭擺動造成振動進而影響到影像的穩定度，此問題將造成成本浪費及增加後續影像處理的問題。而論文中則是設計一振動吸收器去解決此一問題，其設計是利用振動吸收器原理，即外力頻率接近系統固有頻率時，其振動將逐漸變小之特性及參照系統本身的考量去設計，而其振動吸收器內的參數係利用牛頓第二定則及剛體運動學之原理先行推導，並再以matlab軟體將其模擬以得到振動吸振器中的彈性常數與質量等相關參數之最佳化，最後再與真實系統做結合，以探討此方法之可行。最後此方法將能大量實踐應用高頻超音波機械掃描式馬達產業中，並可大幅降低過去線上調整時間並能使成本得以控制。

This paper aims to solve the high-frequency ultrasound scanning motor mechanical scanning in clinical bio-swing caused due to vibration of the probe and thus affect the stability of the image，This problem will result in increased cost of waste and subsequent image processing problems。The paper is to design a vibration absorber to solve this problem，The design principle is the use of vibration absorber，The external frequency close to the system natural frequency，The vibration will gradually become smaller with reference to the characteristics and considerations to design the system itself，While the vibration absorber system within the parameters set using Newton''s second principle is， and rigid body kinematics of the first derivation，And then its simulation matlab software to obtain the vibration absorber in the elastic constants and other parameters of the best quality of，Finally，to do with the real system，To explore the feasibility of this method。Finally， this method will be a lot of practical application of high frequency ultrasound scanning machine in the motor industry，Can significantly reduce the time and make the
last line to adjust the cost to control。
