U形波纹铝管稳定性试验研究

Stability experiment research on U-shape ripple aluminium tube

通过U形波纹铝管稳定性试验研究,探讨了波纹铝管稳定性计算方法,确认波纹铝管承受内压失稳主要形式是柱状失稳和外压条件下因强度不足被压扁而失效。分析了内压径向弯曲应力计算式同样适合外压波纹失效校核计算,并给出了理论和试验数据,供工程设计和选用参考。

?By stability experiment research on Ushape ripple aluminium tube,the stability calculation method of Ushape ripple aluminium tube is discussed.It confirms that pressure instability is mainly caused by column instability and the failure to outer pressureThe calculation formulae for meridional bending stress due to pressure applie can alse be to outer pressure ripple failure calculation,the theory and the experiment data for engineering design and selection reference is also provided
