當(dāng)波紋管兩端都受到限制時(shí)，如果波紋管內(nèi)壓力增大至某一臨界值，波紋管就會(huì)產(chǎn)生失穩(wěn)現(xiàn)象。允許位移；對(duì)于工作在壓縮狀態(tài)的波紋管，它的比較大壓縮位移是：波紋管在壓力作用下，壓縮到波紋之間相互彼此接觸時(shí)所能產(chǎn)生的比較大位移值，也稱為結(jié)構(gòu)允許比較大位移，它等于波紋管自由長度與比較大壓縮長度之差。波紋管不產(chǎn)生塑性變形情況下所能獲得的比較大位移稱為波紋管的允許位移。波紋管在實(shí)際工作過程中會(huì)產(chǎn)生殘余變形，殘余變形又稱長久變形或塑性變形，波紋管在力或壓力作用下產(chǎn)生變形，當(dāng)力或壓力卸除后，波紋管不恢復(fù)原始狀態(tài)的現(xiàn)象稱殘余變形，殘余變形通常用波紋管不恢復(fù)原始位置的量來表示又稱零位偏移。成都PE波紋管一級(jí)經(jīng)銷商如果元件的彈性特性是非線性的，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

承載載荷；作用在金屬波紋管及其它彈性元件上的各種預(yù)期的負(fù)荷值，如集中力F、壓力p和力矩M等。在金屬波紋管類彈性元件使用時(shí)，除給定施加的載荷值外，還須給定載荷的作用方向及作用位置。對(duì)于壓力載荷，還要說明彈性元件是承受內(nèi)腔壓力或外腔壓力。金屬波紋管及其它彈性元件在正常工作條件下允許使用的比較大載荷值或滿量程值。它通常是預(yù)期的設(shè)計(jì)值，或是對(duì)產(chǎn)品原型經(jīng)過實(shí)際檢測后再經(jīng)修定的設(shè)計(jì)值。具體彈性元件產(chǎn)品在工作中經(jīng)受瞬間或試驗(yàn)期間允許超過額定載荷而不發(fā)生損壞、失效、失穩(wěn)時(shí)的承載能力。對(duì)于儀表彈性敏感元件，一般限定超載能力為額定載荷的125%。在工程中使用的波紋管類組件，一般限定在額定載荷的150%。根據(jù)工程要求，當(dāng)要求大的安全系數(shù)時(shí)，使用的彈性元件規(guī)定不允許有任何超載，因此載荷必須小于或等于額定載荷值。 </p><p> 除了上述六種剛度計(jì)算方法之外，國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。活動(dòng)端帶動(dòng)指針即可直接指示壓力的大小。波紋管常常與位移傳感器組合起來構(gòu)成輸出為電量的壓力傳感器。</p><div

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)于不同的場合，為便于分析問題，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；塑料等其他材質(zhì)波紋管在介質(zhì)輸送、電力穿線、機(jī)床、家電等領(lǐng)域有著不可替代的作用。成都日豐波紋管生產(chǎn)</p><p
