除了上述六種剛度計(jì)算方法之外，國(guó)外還有許多種其它的計(jì)算剛度的方法，在此不再介紹。我國(guó)的力學(xué)工作者在波紋管的理論研究和實(shí)驗(yàn)分析方面作了大量工作，取得了豐碩的研究成果。其中**主要的研究方法是：（1）攝動(dòng)法（2）數(shù)值積分的初參數(shù)法（3）積分方程法（4）攝動(dòng)有限單元法上述方法都可以對(duì)波紋管進(jìn)行比較精確的計(jì)算。但是，由于應(yīng)用了較深的理論和計(jì)算數(shù)學(xué)的方法，工程上應(yīng)用有一定的困難，也難于掌握，需要進(jìn)一步普及推廣。金屬波紋管與螺旋彈簧聯(lián)用時(shí)的剛度計(jì)算在使用過(guò)程中，對(duì)剛度要求較大，而金屬波紋管本身剛度又較小時(shí)，可以考慮在波紋管的內(nèi)腔或外部配置圓柱螺旋彈簧。這樣不*可以提高整個(gè)彈性系統(tǒng)的剛度，而且遲滯引起的誤差也可以大為減小。這種彈性系統(tǒng)的彈性性能主要取決于彈簧的特性和波紋管有效面積的穩(wěn)定性。成都聯(lián)塑波紋管規(guī)格型號(hào)如果元件的彈性特性是非線(xiàn)性的，則剛度不再是常數(shù)，而是隨著載荷的增大發(fā)生變化。</p><div

波紋管在工作時(shí)，有的承受內(nèi)壓，有的承受外壓，例如波紋膨脹節(jié)和金屬軟管在多數(shù)情況下其波紋管承受內(nèi)壓，而用于閥門(mén)閥桿密封的波紋管一般情況下承受外壓在這里主要分析波紋管承受內(nèi)壓時(shí)的應(yīng)力，波紋管承受外壓的能力一般情況下高于耐內(nèi)壓能力。隨著波紋管的廣泛應(yīng)用，人們對(duì)波紋管的應(yīng)力進(jìn)行大量的分析研究和實(shí)驗(yàn)驗(yàn)證工作，提出了許多供工程設(shè)計(jì)使用的計(jì)算公式、計(jì)算程序和圖表。但是，有的方法由于圖表或程序繁復(fù)使用不方便，有的方法假設(shè)條件不是過(guò)于簡(jiǎn)化就是過(guò)于理想，難以保證使用上的安全可靠，不少方法未能為工程界所接受。因此，真正符合實(shí)用要求的方法為數(shù)不多。應(yīng)用比較普遍的方法有如下兩種； </p><p> 靈敏度；金屬波紋管及其它彈性元件承受單位載荷時(shí)所產(chǎn)件的位侈量稱(chēng)為元件的靈敏度。剛度和靈敏度是波紋管及其它彈性元件的主要功能參數(shù)，但它們又是同一使用特性的兩種不同的表示方法。對(duì)于不同的場(chǎng)合，為便于分析問(wèn)題，可采用其中任何一種參數(shù)。有效面積；對(duì)于實(shí)現(xiàn)壓力一力或力一壓力轉(zhuǎn)換的彈性元件，還有一個(gè)重要的功能指標(biāo)是有效面積。有效面積是指彈性元件在單位壓力作用下，當(dāng)其位移為零時(shí)所能轉(zhuǎn)換成集中力的大小。使用壽命；金屬波紋管與螺旋彈簧聯(lián)用時(shí)的剛度計(jì)算；</p><div

根據(jù)工作壓力性質(zhì)的不同，波紋管的允許位移也有所區(qū)別一般波紋管只承受軸向載荷（拉力或壓力）時(shí)，它的允許位移可在波紋管有效長(zhǎng)度的10%~40%之間選用；而在波紋管承受橫向集中力、扭轉(zhuǎn)力矩或綜合受力時(shí)，波紋管的允許位移應(yīng)適當(dāng)減小。應(yīng)用多層波紋管可以降低剛度和變形引起的應(yīng)力，因而可以在很大程度上提高波紋管的壽命。波紋管在其它情況相同而工作壓力性質(zhì)（恒定或交變載荷）不同的條件下工作時(shí)，其使用壽命將有差別。顯然，在交變載荷下工作時(shí)，波紋管的壽命比恒定載荷下工作時(shí)要短一些。四川川路塑膠波紋管</p></p><br
