摘要
校直行程计算是压力校直工艺的关键技术,本文阐述了校直行程计算的3种方法。根据压力校直过程的理论模型,通过简化和推导,对校直行程的经验计算公式进行了理论依据分析,给出了经验公式的理论解释,为自动校直机的开发研制提供了技术支持。有限元实例计算证实了分析的正确性。
Three calculating methods of straightening stroke have been described. Based on theoretical model of press straightening process, theoretical basis of empirical formula calculating straightening stroke has been analyzed and theoretical explanation of empirical formula given.It is helpful for design and development of automatic straight-ener. Accuracy of analysis has been proved by an example calculated by FEM.
