style="text-indent:25px">當來流速度接近或超過聲速時，會產(chǎn)生激波，帶來額外的激波阻力。本質上說，激波阻力也是一種壓差阻力，是由于激波的存在，使物體后半部的壓力恢復不夠而造成的。忽略黏性損失，當沒有激波時，氣流在物體后半部減速對應一個壓升Δp1 ；當存在激波時，氣流經(jīng)過激波時部分損失了部分機械能，同樣的減速對應的壓升Δp2 就會比Δp1 要小。因此，有激波時物體后半部的壓力要低一點，這就是激波阻力的來源。把物體前緣做成尖的可以減小激波錐角，從而減小激波帶來的損失，也就減小了激波阻力。船在水面行進時會產(chǎn)生水面波，也會有波阻力，所以要做成尖頭的，而在水下行進的潛艇則是圓頭的。流體在流動時，相鄰流體層間存在相對運動，流體層之間會產(chǎn)生摩擦阻力，成為粘滯力。浙江電纜卷筒流體器材</p><p

style="text-indent:25px">聯(lián)軸器是將兩軸軸向聯(lián)接起來并傳遞扭矩及運動的部件并具有一定的補償兩軸偏移的能力，為了減少機械傳動系統(tǒng)的振動、降低沖擊尖峰載荷，聯(lián)軸器還應具有一定的緩沖減震性能。聯(lián)軸器有時也兼有過載安全保護作用。聯(lián)軸器屬于機械通用零部件范疇，用來聯(lián)接不同機構中的兩根軸（主動軸和從動軸）使之共同旋轉以傳遞扭矩的機械零件。在高速重載的動力傳動中，有些聯(lián)軸器還有緩沖、減振和提高軸系動態(tài)性能的作用。聯(lián)軸器由兩半部分組成，分別與主動軸和從動軸聯(lián)接。一般動力機大都借助于聯(lián)軸器與工作機相聯(lián)接，是機械產(chǎn)品軸系傳動較常用的聯(lián)接部件。20世紀后期國內(nèi)外聯(lián)軸器產(chǎn)品發(fā)展很快，在產(chǎn)品設計時如何從品種甚多、性能各異的各種聯(lián)軸器中選用能滿足機器要求的聯(lián)軸器，對多數(shù)設計人員來講，始終是一個困擾的問題。常用聯(lián)軸器有膜片聯(lián)軸器，鼓形齒式聯(lián)軸器，萬向聯(lián)軸器，安全聯(lián)軸器，彈性聯(lián)軸器及蛇形彈簧聯(lián)軸器。浙江流體產(chǎn)品工廠</p></p><br
