金屬波紋管作為彈性密封零件，首先要滿足強(qiáng)度條件，即其比較大應(yīng)力不超過給定條件下的許用應(yīng)力。許用應(yīng)力可由極限應(yīng)力除以安全系數(shù)得出。根據(jù)波紋管的工作條件和對(duì)它的使用要求，極限應(yīng)力可以是屈服強(qiáng)度，也可以是波紋管失穩(wěn)時(shí)的臨界應(yīng)力，或者是疲勞強(qiáng)度等。要計(jì)算波紋管比較大工作應(yīng)力必須分析波紋管管壁中的應(yīng)力分布。波紋管上的應(yīng)力是由系統(tǒng)中的壓力和波紋管變形所產(chǎn)生的。壓力在波紋管上產(chǎn)生環(huán)（周向）應(yīng)力，四川華邦波紋管定制，而在波的側(cè)壁、波谷和波峰處產(chǎn)生徑向的薄膜和彎曲應(yīng)力。不能抗彎的薄殼有時(shí)稱為薄膜，四川華邦波紋管定制，忽略彎曲而算得的應(yīng)力則稱為薄膜應(yīng)力，四川華邦波紋管定制。波紋管變形時(shí)產(chǎn)生徑向薄膜應(yīng)力和彎曲應(yīng)力。波紋管適于測(cè)量低壓。四川華邦波紋管定制</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)條件不是過于簡(jiǎn)化就是過于理想，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；四川本地波紋管根據(jù)波紋管的工作條件和對(duì)它的使用要求，極限應(yīng)力可以是屈服強(qiáng)度。</p><div

</p><p> 波紋管位移與零位偏移之間的關(guān)系，無論拉伸還是壓縮位移，在波紋管位移的起始階段，它的殘余變形量都很小，一般都小于波紋管標(biāo)準(zhǔn)中規(guī)定的允許零位偏移值。但是，當(dāng)拉伸（或壓縮）位移量逐漸增大到超過一定的位移值后，會(huì)引起零位偏移值的突然增大，這表示波紋管產(chǎn)生比較大的殘余變形，在這之后．如果再增大一點(diǎn)位移量，殘余變形將明顯增加。所以波紋管一般不應(yīng)超過這個(gè)位移量，不然將會(huì)嚴(yán)重的降低其精度、穩(wěn)定性和可靠性以及使用壽命。波紋管用于力平衡式儀表時(shí)，其有效面積的穩(wěn)定性會(huì)直接影響著儀表的精度。</p><div
