开发了三种不同的模型来确定材料在轧辊矫直操作中所经历的加载模式（有限元方法，解析模型和半解析模型）。研究表明，半解析模型更适合于确定轧辊矫直机的参数，解析模型足以确定矫直机的尺寸。一个特定的实验测试装置，软（板振荡弯曲测试），也被设计和用于确定钢板在不同加载模式下的机械响应过程。介绍了该设备，并提出了材料参数识别方面的第一个结果，用于进一步分析和优化轧辊矫直机工业装置。
Three different models are developed to determine the loading modes experienced by the material in roll levelling operations (a finite element approach, an analytical and a semi-analytical model). This study shows that the semi-analytical model is the more appropriate in order to determine the parameters of rolls levellers and the analytic one is sufficient to define the size of the levellers. A specific experimental testing set-up, SOFT (Sheet Oscillatory Flexion Test), has also been designed and used to determine the mechanical response of steel sheets under the different loading modes of the process. The equipment is described and the first results in terms of materials parameters identification are presented, for further analysis and optimisation of roll leveller industrial set-ups.
