为了提高中厚板矫直过程中矫直力的精度，对中厚板矫直机矫直过程中的中性层偏移规律进行了系统分析，推导出中性层偏移计算公式。中性层偏移公式说明，在矫直过程中，中性层偏移受弹区比和偏移系数的影响较大，故本文以40 m m板厚矫直过程为例，分析了弹区比和偏移系数对中性层偏移及弯曲力矩的影响，并做了误差对比分析。研究结果表明：当弹区比在15％～40％时，矫直效果最佳，在这个范围内，由于中性层偏移造成的误差达到了10．09％。因此，在辊式矫直过程中，为得到更精确的弯曲力矩和矫直力，中性层偏移量是不可忽略的影响因素。

In order to improve the precision of straightening force ,the neutral layer offset induced in the straightening process was analyzed systematically .The formula of the neutral layer offset was obtained .It shows that the elastic region rate and the coeffi‐cient of the offset have large influence on the neutral layer offset .Take the straightening process of a 40 mm thick plate as exam‐ple ,the influence of elastic region rate and coefficient of the offset on the neutral layer offset was analyzed .The results showed that the straightening effect is the best when the elastic region rate is 15%‐40% .In this range ,the error caused by the neutral layer offset reaches 10 .09% .Therefore ,the factor of neutral layer offset cannot be ignored in order to obtain more accurate straightening moment and straightening force .
