逐层迭代法计算卷取机卷筒单位压力

Calculating drum′s unit pressure by the iteration of layer by layer

卷取机卷筒单位压力的计算是卷取机设计中的关键问题 ,考虑钢卷径向紧密系数沿径向变化的特性 ,采用逐层迭代计算法 ,对卷取机卷筒单位压力进行更精确的计算。

The calculation of the drum′s unit pressure is the key problem in the design of coiler.With a view to the character that the radial compression coefficient varies with the radius of a coil, the iteration of layer by layer is taken to calculate the pressure at the coiler′s drum. An actual measurement proves that the method makes the result closer to the fact.
