冷轧带钢因内部残余应力分布不均造成各种屈曲模态的板形缺陷。求解这一屈曲过程需要构造合理的初始位移函数。另外,板形平直度自动控制也必须依据符合实际的浪形理论。本文用BLD—90激光测距仪精确地实测了冷轧宽带钢生产中出现的各种浪形,经最小二乘曲面拟合分析,抽象出满足上述要求的浪形函数的通式和对应特定浪形的具体表达式。
Cold-rolled strip due to uneven distribution of internal residual stress caused by a variety of buckling mode plate defects. Solving this buckling process needs to construct a reasonable initial displacement function. In addition, flatness flatness automatic control must also be based on the actual wave theory. In this paper, BLD-90 laser range finder was used to accurately measure the various wavy shapes in the cold-rolled wide strip steel. The least-squares surface fitting analysis was used to abstract the general formulas and corresponding special Wave-shaped concrete expression.
