波紋管種類波紋管主要包括金屬波紋管、波紋膨脹節(jié)、波紋換熱管、膜片膜盒和金屬軟管等。金屬波紋管主要應(yīng)用于補償管線熱變形、減震、吸收管線沉降變形等作用，***應(yīng)用于石化、儀表、航天、化工、電力、水泥、冶金等行業(yè)。塑料等其他材質(zhì)波紋管在介質(zhì)輸送、電力穿線、機床、家電等領(lǐng)域有著不可替代的作用。 </p> <p> 波紋管:壓力測量儀表中的一種測壓彈性元件。它是具有多個橫向波紋的圓柱形薄壁折皺的殼體，波紋管具有彈性，在壓力、軸向力、橫向力或彎矩作用下能產(chǎn)生位移。波紋管在儀器儀表中應(yīng)用***，主要用途是作為壓力測量儀表的測量元件，將壓力轉(zhuǎn)換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數(shù)十帕至數(shù)十兆帕。另外，波紋管也可以用作密封隔離元件，將兩種介質(zhì)分隔開來或防止有害流體進入設(shè)備的測量部分。它還可以用作補償元件，利用其體積的可變性補償儀器的溫度誤差，成都穿線管康泰定制廠家。有時也用作為兩個零件的彈性聯(lián)接接頭等。波紋管按構(gòu)成材料可分為金屬波紋管、非金屬波紋管兩種;按結(jié)構(gòu)可分為單層和多層。單層波紋管應(yīng)用較多。多層波紋管強度高，耐久性好，成都穿線管康泰定制廠家，應(yīng)力小，用在重要的測量中。波紋管的材料一般為青銅、黃銅、不銹鋼、蒙乃爾合金和因康鎳爾合金等，成都穿線管康泰定制廠家。生態(tài)康泰,更是人的生態(tài)。成都穿線管康泰定制廠家</p><div

假定波紋管的全部波紋都處于同一條件下，在計算時只研究波紋管波紋的單個半波。這樣，在研究中就不考慮端部波紋，雖然端部波紋的邊界條件與中間波紋有所不同。數(shù)值法是根據(jù)E.列斯涅爾對于變壁厚回轉(zhuǎn)薄殼產(chǎn)生軸向?qū)ΨQ變形時所列的非線性方程來解的。在推導(dǎo)E.列斯涅爾方程時，應(yīng)用了薄殼理論的一般假定，其中包括:與環(huán)殼曲率主半徑相比厚度很小的假定;材料的均一性和各向同性的假定。采用上述假定也會給計算帶來一定的誤差。因為在制造波紋管時，管坯的軋制，拉深和隨后的波紋塑性成形會造成材料力學性能上的各向異性和不均勻性。 </p> <p> 2.美國EJMA 應(yīng)力計算方法 </p> <p> 波紋管的有效面積計算 </p> <p> 有效面積是波紋管的基本性能參數(shù)之一，它表征波紋管將壓力轉(zhuǎn)換為集中力的能力，在利用波紋管把壓力變成集中力輸出的場合，有效面積就是一個重要參數(shù)。 </p> <p> <br />
