在工作中涉及到的圖形設(shè)計中可以歸為LOGO的圖形設(shè)計，圖標(biāo)的圖形設(shè)計，控件的圖形設(shè)計。怎么將流體運(yùn)用到這些圖形設(shè)計當(dāng)中去？我們接下來可以進(jìn)一步分析拆解。 LOGO的流體表現(xiàn): logo圖形設(shè)計的時候常常會根據(jù)產(chǎn)品的名字表達(dá)的含義，字母進(jìn)行創(chuàng)造和融合，但往往含義，字母的視覺表達(dá)都不是流體形狀的，這時加入流體性質(zhì)，設(shè)計含義和字母便很好的將圖形豐富出來。流動感的logo能表示自由，創(chuàng)新，科技等，所以可以將這些特性融入到產(chǎn)品特性中去。功能性ICON: 功能性圖標(biāo)注重簡化且表達(dá)完整和美觀，流體可以很好的打造這一些，因為流體的設(shè)計本身就自帶美觀，在簡化和表達(dá)完整融合上流體也能更好的鏈接起來。為了和常規(guī)圖標(biāo)做區(qū)分也可以加入流體，在一篇文章圖標(biāo)創(chuàng)意拆解里面就可以應(yīng)用流體，那是一個微信的愛心圖標(biāo)，但融入彩帶般的流體后將簡單的愛心圖標(biāo)豐富了起來，也通過彩帶的含義表達(dá)了公益的精神，經(jīng)典。常用流體設(shè)備廠家機(jī)翼理論的正確性，使人們重新認(rèn)識無粘流體的理論，肯定了它指導(dǎo)工程設(shè)計的重大意義。</p><div

style="text-indent:25px">絕大多數(shù)聯(lián)軸器均已標(biāo)準(zhǔn)化或規(guī)格化。設(shè)計者的任務(wù)是選用，而不是設(shè)計。選用聯(lián)軸器的基本步驟如下：根據(jù)傳遞載荷的大小，軸轉(zhuǎn)速的高低，被聯(lián)接兩部件的安裝精度等，參考各類聯(lián)軸器特性，選擇一種合用的聯(lián)軸器類型。 1、所需傳遞的轉(zhuǎn)矩大小和性質(zhì)以及對緩沖減振功能的要求。例如，對大功率的重載傳動，可選用齒式聯(lián)軸器；對嚴(yán)重沖擊載荷或要求消除軸系扭轉(zhuǎn)振動的傳動，可選用輪胎式聯(lián)軸器等具有高彈性的聯(lián)軸器。 2、聯(lián)軸器的工作轉(zhuǎn)速高低和引起的離心力大小。對于高速傳動軸，應(yīng)選用平衡精度高的聯(lián)軸器，例如膜片聯(lián)軸器等，而不宜選用存在偏心的滑塊聯(lián)軸器等。</p><p style="text-indent:25px">流體性質(zhì)：粘滯性當(dāng)流體中發(fā)生了層與層之間的相對運(yùn)動時，速度快的層對速度慢的層產(chǎn)生了一個拖動力使它加速，而速度慢的流體層對速度快的就有一個阻止它向前運(yùn)動的阻力，拖動力和阻力是大小相等方向相反的一對力，分別作用在兩個緊挨著但速度不同的流體層上，這就是流體粘性的表現(xiàn)，稱為內(nèi)摩擦力或叫粘滯力。為了維持流體的運(yùn)動就必須消耗能量來克服由于內(nèi)摩擦力產(chǎn)生的能量損失，這就是流體運(yùn)動時會造成能量損失的原因。實際上，粘性是流體阻止發(fā)生剪切變形和角變形的一種特性。這是由于內(nèi)聚力的存在和流體層間的動量交換而造成的。內(nèi)摩擦力就是這種特性的表現(xiàn)形式。當(dāng)流體處于靜止或各部分之間相對速度為零時，流體的粘性就表現(xiàn)不出來，內(nèi)摩擦阻力也就等于零。流體的基本特征是沒有一定的形狀并且具有流動性。</p><div

style="text-indent:25px">普朗特學(xué)派從1904年到1921年逐步將N-S方程作了簡化，從推理、數(shù)學(xué)論證和實驗測量等各個角度，建立了邊界層理論，能實際計算簡單情形下，邊界層內(nèi)流動狀態(tài)和流體同固體間的粘性力。同時普朗克又提出了許多新概念，并多地應(yīng)用到飛機(jī)和汽輪機(jī)的設(shè)計中去。這一理論既明確了理想流體的適用范圍，又能計算物體運(yùn)動時遇到的摩擦阻力。使上述兩種情況得到了統(tǒng)一。機(jī)翼理論和邊界層理論的建立和發(fā)展是流體力學(xué)的一次重大進(jìn)展，它使無粘流體理論同粘性流體的邊界層理論很好地結(jié)合起來。隨著汽輪機(jī)的完善和飛機(jī)飛行速度提高到每秒50米以上，又迅速擴(kuò)展了從19世紀(jì)就開始的，對空氣密度變化效應(yīng)的實驗和理論研究，為高速飛行提供了理論指導(dǎo)。流體粘度高的，分子好比5年后的雷神，走不動道，移動起來十分緩慢。廣東軟管流體設(shè)備廠家</p><p

style="text-indent:25px">流體性質(zhì)：壓縮性和膨脹性當(dāng)作用在流體上的壓力增加時，流體所占有的體積將減小，這種特性稱為流體的壓縮性。通常用體積壓縮系數(shù)Bp來表示。Bp指的是在溫度不變時，壓力每增加一個單位，單位體積流體的體積變化量。當(dāng)溫度變化時，流體的體積也隨之變化，溫度升高、體積膨脹，這種特性稱為流體的膨脹性，用溫度膨脹系數(shù)Bt來表示。Bt是指當(dāng)壓力保持不變溫度升高1K時單位體積流體的體積增加量。一般的，水及其他液體的壓縮系數(shù)和膨脹系數(shù)都很小。所以，工程上一般不考慮它們的壓縮性或膨脹性。但當(dāng)壓力、溫度的變化比較大時(如在高壓鍋爐中)，就必須考慮液體的壓縮性和膨脹性。對于氣體，它不同于液體，壓力和溫度的改變對氣體密度或重度的變化影響很大。在熱力學(xué)中是用氣體狀態(tài)方程式來描述它們之間的關(guān)系。廣東軟管流體設(shè)備廠家</p></p><br
