不偏不倚--奈米級修準方法與敏感度評估之研究

Positive –A Study on a Nanoscale Revision Method and Sensitivity Evaluation This paper took a pyramid and a fixed point as the reference level. It was the intention of our team to establish and prove a new hardness value revising method that is to be used in the deflection of indentation of nano indentor. Such new method was named Material Surface Nanoscale Hardness Revision Method with which we re-measured various materials and error sensitivity of hardness values. We obtained the following conclusions:(1). This paper revision modification method have a highly precision. (2). When the round tip or plane tip was closed to ideal indentor tip, the contact areas during indentation process were close, not demonstrating significant difference. (3). The indentation triangle created when loading effort P was similar with the one left on the sample material when unloading the effort; thus, even though the sink-in and pile up effects due to the mechanical properties of sample material caused the differentiation of side lengths and two indentation areas, the angles of two indentation areas was the same. (4). When the effort was loaded by the tip onto the sample material, if the tip had a certain deflection ψ or rotation ω, the indentation triangle left on the sample material was still significant. (5). In the observation of the indentation triangle left on the sample material, when the triangle cannot become a regular triangle, it meant that there is a deflection or rotation happening to the tip and a further revision of the deflected angle ψ or rotated angle ω is required. (6). The hardness value revision method under indentation deflection situation had the best effect on the projected area revision; the second was on the indentation volume revision and than on the indentation contact area revision. (7). The hardness error sensitivity of hardness value revision method under indentation deflection situation had the best effect on the projected area; the second was on the contact area and than on the indentation volume revision. (8). The method proposed by this study was proved by the silica and aluminum single crystal indentation results and is thus able to be applied to the engineering in the nanoscale measurement of metal materials to obtain more precise data.不偏不倚-奈米級修準方法與敏感度評估之研究在這篇研究報告中,以一個三角錐和一個定點為基準,本團隊建立並證明一個新的在奈米硬度測試儀壓痕偏斜情況下,硬度值的修正方法,取名材料表面奈米硬度修正方法。在新的材料表面奈米硬度修正方法下,重新檢測各種材料及硬度誤差敏感度,得到許多好的結論:(1)本研究之修準方法具有高度精確性。(2)利用圓球尖端或平面尖端的方法近似理想壓頭時其壓痕過程中之接 觸面積相近,並無明顯差異。(3)作用力P 施加(Loading)時之壓痕三角形與卸載時(unloading)殘留於測試材料上之壓痕三角形係屬於相似形;因此,即使各該三角形之邊長因為該測試材料本身的機械性質所產生的滲入(sink-in)與堆放(pile-up)的效應而造成作用力施加與卸載時,壓痕面積上的差異。不過,該兩壓痕面積的角度卻是一致的。(4)當該作用力隨著該壓頭施加於測試材料時,若該壓頭產生某一程度的偏斜ψ 或旋轉ω 時,該殘留於測試材料上之壓痕三角形仍然具有代表性。(5)藉由觀察該殘留於測試材料上之壓痕三角形,當該三角形無法成為一正三角形時,其係表示壓頭已產生偏斜或旋轉的之情況,需要進一步對該偏斜角度ψ 或旋轉角度ω 進行修正。(6)在壓痕偏斜情況下硬度值的修正方法以投影面積修正為最佳,其次是壓痕體積再其次是壓痕接觸面積方法作修正。(7)在壓痕偏斜情況下硬度值修正方法的硬度誤差敏感度則以投影面積為最佳,其次是接觸面積再其次是壓痕體積修正方法。(8)本研究提出之修正方法經由矽、鋁單晶壓痕結果驗證,足以說明適用於工程學上金屬材料進行奈米壓痕硬度檢測時更精確的數據獲得。

肘節式駐腳架

我媽媽體重只有38公斤,每次她在牽機車一直在抱怨車子好重,媽媽因為個子很矮,只有150公分,而且她每次又喜歡穿高跟鞋,所以每次在騎機車、牽機車,而且她又怕車子cc數太小容易被風吹倒,自己又喜歡騎150cc的機車(機車重量一般為70kg~250kg),每次牽機車時自己還常常牽到跌倒,跌倒曾經有一次跌到骨折住院(技術真差!),或每天在喊著關節痛、腰酸背痛,我對我媽媽的行為都感到很辛苦,機車有那麼重嗎?結果我自己牽才知道有那麼重,所以我一直在想,在媽媽的抱怨,體重38公斤、身高150公分這麼瘦弱的女孩子,又騎著150cc的機車,說真的機車的腳架對她來講受力實在太大,所以我一直在想怎麼去設計一個機車腳架,可以讓媽媽不再那麼痛苦、不再有那麼多的抱怨!甚至穿高跟鞋也很好用,所以我一直在想機車腳架怎麼去使用它,直到機械科二年級我上了機件原理裡面有解說機構,我想所有的機車駐車架都是用力矩原理,那為什麼我們不在力矩原理再加上使用肘節機構(Toggle mechanism),因為機件原理講肘節機構是最省力,肘節機構當它形成一直線的時候力量最大,所以我利用高職所學的所有的東西來設計肘節機構設計一個省力的機車腳架,使媽媽不再痛苦、讓媽媽很輕易的就把機車立起來,這就是我的設計---- 肘節式(Toggle mechanism)駐車架。

Graphene Nanoplatelet-Embedded Acrylic Paint for Low Cost Waterproof Paintable Capacitive Sensors and Free Standing Supercapacitors

Modern capacitive touch input and proximity sensing technologies are rigid and limited to flat substrates making it impossible to apply them onto objects with irregular geometries like textiles or car handles. Furthermore, the high cost restricts the applications to small surfaces and cannot be scaled up to be applied on large surfaces such as walls. Therefore, a paint-on scheme would broaden the applications of capacitive touch input and proximity sensing devices. Paintable capacitive sensors are an emerging technology hindered by the high cost and lackluster properties of conductive paints. Existing conductive paints utilize expensive filler materials such as silver and gold to achieve high conductivity but suffer from low surface area. High surface area is critical for capacitive proximity sensors to detect objects from far distances and for overall sensitivity. Carbonaceous alternatives using micronized graphite exhibit low conductivity, require high loadings and most disintegrate when in contact with water. Multilayer graphene nanoplatelets are investigated for their high conductivity, high surface area, low cost, flexibility and eco friendliness. A waterproof acrylic latex is combined with multilayer graphene and dispersed via bath sonication. The optimal time of sonication and optimal graphene loading is determined through systematic testing. An Arduino Uno is loaded with a CapSense library and the graphene based paint is utilized as the interface to sense both touch and proximity.

Experimental Study on Vibration Mitigation of Structure by Utilizing Paraboloidal Tank Tuned Liquid Damper (TLD)

本研究以自製模型模擬「結構物裝設拋物體液槽阻尼器(TLD)」。此TLD以多個拋物面容器組成,實驗評估其容器曲率、盛水深、盛水質量比(水質量/總質量)及結構物振幅等參數對減振效應的影響。在不同曲率容器內調整盛水深,使「水體自然擺盪頻率」接近「結構物振動頻率」;水體強烈擺盪時易觀察到水面碎波現象,衍生側向擾動,使水體旋轉,此時「旋轉頻率」亦幾乎等於「結構物振動頻率」,產生更大之共振效應,因此水體可提供較大反向作用力,增加減振效果。結構物振幅越大,水體旋轉可能性越高,減振效應越顯著;增加盛水質量比亦減振效果較佳。但水體旋轉時,結構物亦產生側向位移,因此於容器底部加裝潛沒式導流板,可有效控制液體旋轉方向,使其成對異向旋轉,減低結構物側向位移量。實驗證實藉調整拋物面容器之TLD的上述參數,可有效達到減振效果。

電場中的小晶靈-高電壓電場中液滴的結晶現象

本研究設計相機-顯微鏡-玻璃座平行銅片電場裝置,拍攝鹽類液滴在高電壓電場中的結晶現象,並以色階曲線為基礎,發展出SCL值,來偵測晶體表面的性質。實驗先找到能讓晶體成長趨向單顆且高透明的條件為:加蓋(低蒸發速率)、過濾、無施加電場與低熱LED光源。並應用蒸發速率差異,發現食鹽晶體的變速成長現象。蒸發快會形成階梯螺旋紋,蒸發慢,紋路消失,變成全透明晶體。將這裝置轉放在高電壓電場下可發現:晶體形狀發生改變(晶體傾斜或碎晶),透光度變差(SCL值變小),可觀察到新生晶體邊緣,有條狀暗紋出現,但晶體成長速率變化不大。鹽晶析出反應會因些微的外在變化,而影響溶液中離子堆疊,在晶體表面出現陰影或不規則紋路。這種對外在環境有著高度反應的現象,可以透過反應位能曲線圖來解釋,正可以用來研究外界高壓電場如何對物質發生影響。
