Study on Numerical Simulation for Control of Winding Process of Thin Wall Spiral Tube

Being aimed at the inside wall wrinkling and sinking phenomenon of palladium-yttrium alloy thin wall spiral tube used for preparation of high purity hydrogen,extraction of hydrogen isotope,and purification and separation of hydrogen in the winding process,this article analyzed the reasons for above phenomena,established a numerical simulation model of winding process of above tube,using elastic-plastic Finite Element method analyzed the max.tensile stress and max.compression stress and their locations,thereby provides a theory base for the control of working forming course of thin wall spiral tube.
