胀缩式卷筒是现代卷取机的关键部件,其卷取带钢的过程是一个非常复杂的弹塑性大变形过程,既有材料非线性、几何非线性,又有边界条件的非线性,变形机理非常复杂,难以用数学模型来准确地描述。文中采用商用有限元软件对胀缩卷筒卷取过程进行了动态模拟,并分析计算了胀缩式卷筒卷取过程中径向压力,卷筒扇形块的径向位移等,分析计算的结果对于胀缩式卷筒的设计具有指导意义。 Swelling reel is a key part of the modern coiler. The process of coiling the strip is a very complex elasto-plastic large deformation process. It not only has material nonlinearities, geometric nonlinearities, but also non-linear boundary conditions, Deformation mechanism is very complicated, it is difficult to use mathematical models to accurately describe. In this paper, the commercial finite element software was used to simulate the process of take-up and rewinding of the swell-and-shrink reel, and the radial pressure and the radial displacement of the reel fan were analyzed and calculated. The results of the analysis and calculation It is instructive for the design of swell-and-shrink reel.
