摘　　要：采用精确的小孔松弛法，实测了某１７００ｍｍ冷连轧机生产中取样带钢在离线状态下的横向内应力分布。根据所得结论建立一种修正的有限纤维条原理内应力计算模型，其计算结果和实测值较为吻合。The transversal internal stress distribution in the off-line cold rolled strips sampled for a 1700mm cold tandem mill was measured by the modified hole-drilling technique. Based on the conclusions drawn from the experiment, an available method for calculation of the internal stress distribution was established, which can give fairly identical solution with the test. This numerical method for transversal internal stress calculation can be used in the on-line automatic flatness control.
