摘要： 根据仿真模型的校核、验证及验收理论和主要技术,结合冷连轧轧制过程的特点,对轧制力仿真模型的校核、验证和验收过程进行了简化.提出了适合轧制力仿真模型的可信度评估方法:不等式系数法与灵敏度分析法相结合的方法,即首先定义了仿真模型的TIC值,并用现场采集的轧制数据计算轧制力模型的TIC值,依据TIC值判断轧制力模型是否适合于当前的轧制条件,据此定性分析仿真模型的适用性;然后用灵敏度分析法定量分析仿真模型输入参数集对输出的敏感性,两种方法相辅相成,就能准确地验证轧制力模型的有效性.仿真实例与冷连轧生产线所采用的轧制力模型的实际情况相吻合.

Abstract: According to the main theories and technologies of simulation models, the VV&A (verification, validation and accreditation) of cold-rolling force model were simplified considering the characteristics of continuous cold-rolling. An evaluation method of the confidence level of cold-rolling force model is thus presented as follows, which combines inequality coefficient method with sensitivity analysis. The definition of TIC (Theil inequality coefficient) value is given first to justify the cold-rolling force model for simulation, and the TIC value of the model is computed with the data acquired in site to analyze qualitatively the applicability of simulation model. Then, the sensitivity of input parameters to output values is analyzed quantitatively. The validity of the cold-rolling force model is therefore verified by both the qualitative and quantitative ways. The simulation results via exemplification show that they are actually in line with the rolling force model applied to the continuous cold-rolling process.
