| 摘 要： | 某公司在生产某钢号薄板(厚度大于0.35mm)时容易产生起拱现象,而导致产品报废。为了找出产生此缺陷的原因,通过应力释放法中的钻孔法对薄板表面的残余应力进行测试,结果发现薄板加工过程中的某工序使薄板表面产生较大的残余应力而且其分布也不均匀,这是导致薄板最终产生缺陷的主要原因。

| Abstract: | Sheet metal often turns vaulted when its thickness is more than 0 35mm which happens in the production in one corporation, which makes the products unqualified. In order to find out the cause that leads to the default, residual stress on the surface of sheet metal after every working procedure is measured by the Hole drilling Method. The results show that a certain working procedure makes much more residual stress and its distribution is asymmetric on sheet metal surface in sheet metal working process. That is the main reason to make sheet metal unqualified. |
