金屬軟管一端采用波紋管固定
Publisher:admin  Date:2012/12/18 14:32:18  Click:4512

  對(duì)金屬軟管靜態(tài)特性進(jìn)行有限元分析得到了靜態(tài)特性曲線,并將結(jié)果與試驗(yàn)結(jié)果進(jìn)行比較驗(yàn)證了有過渡波時(shí)其結(jié)果與試驗(yàn)結(jié)果更接近,說明了加過渡波的金屬軟管,有限元模型更合理為進(jìn)一步研究提供了更為合理的有限元模型。

  網(wǎng)套能夠承受拉伸、壓縮、彎曲、扭轉(zhuǎn)等特性符合網(wǎng)套的受力特征,每個(gè)節(jié)點(diǎn)具有6個(gè)自由度能夠很好的表征網(wǎng)套,在波紋管上的滾動(dòng)和滑動(dòng)的特征在波紋管兩端部建立過渡波,有效降低了在端部網(wǎng)套的應(yīng)力集中在波紋管的兩端部增大了網(wǎng)套的編制角起到限制端部網(wǎng)套的大幅度滑移,在金屬軟管的一端采用波紋管全部固定,另一端施加各種約束條件在波紋管與網(wǎng)套之間,利用約束方程建立耦合關(guān)系。
