Abstract

During a multi-stage press hardening process, where a metal sheet undergoes rapid austenitization, tempering, and forming, the spatial-temporal temperature development is a driving factor and its control enables it to reach desired product properties. A two-dimensional model extension is proposed, which enables a precise and computationally efficient temperature modeling along the whole metal sheet. Thereupon, a Kalman filter with a time-varying stage dependent output matrix is used to estimate the spatial-temporal temperature development of the sheet based on measurements from a thermal imaging camera. Both the proposed modeling approach and the estimation scheme are validated experimentally.

级进模多段冲压硬化的二维板料温度估算[j]

在多阶段的挤压硬化过程中，金属板材经历快速的奥氏体化、回火和成形，时空温度的发展是驱动因素，其控制使其达到所需的产品性能。提出了一种二维模型的扩展，使得沿整个金属板的温度建模精确且计算效率高。在此基础上，基于热像仪的测量数据，采用具有时变阶相关输出矩阵的卡尔曼滤波来估计薄片的时空温度变化。实验验证了所提出的建模方法和估计方案。
