摘要
为了减小CCY-84型磁测应力仪残余应力递推公式中累积误差对计算结果的影响,针对两端自由边界的工件,基于同一测点应力与其测量顺序无关的思路提出了改进的计算方法,并在实际测量770mm×1200mm×2820mm球墨复合铸铁轧辊工作层残余应力中得到了应用。
With the purpose to reduce influence of accumulative error from the recurrence formula of residual stress measured with magnetic stress meter on the calculation result,based on the consideration that the stress at a same measuring point has no relation to the measuring order,the author proposed an improved calculation method for the work piece with free boundaries on both ends.The new method has been applied to the practical measurement of the residual stress in working layer of a 770 mm×1 200 mm×2 820 mm ductile iron combined roller.
