Simulation of Coil Wedge Effects in Sheet Rolling

该奖项的研究目标是使用一种新的混合有限元方法来研究和模拟板卷轧制和卷取操作中的卷取楔的动态效应。 研究方法是采用一种快速、新型的混合有限元模型来预测轧机挠度。 将这种新方法与线圈绕组模型、工业数据和随机分析相结合，将能够对线圈楔问题进行彻底的调查。研究工作将把快速的新型混合有限元模型与两家轧机制造商和一家主要金属生产商的运行数据和专业知识结合起来。如果成功，其好处和更广泛的影响将包括能够以更高的效率和更低的能耗轧制出上级产品。研究成果将直接为特种金属板带生产商和特种米尔斯轧机制造商提供有益的参考。 更高质量、更高效生产的钢、铝、铜和黄铜线圈的最终用户也将从研究中受益。 此外，这项工作将使不同的学生群体接触到金属制造课程和令人兴奋的金属工业研究。 赖特州立大学将利用其现有的外展计划，鼓励妇女，少数民族和残疾学生在金属轧制领域开展工作，并为增强的职业机会做好准备。 模拟结果解释了线圈楔问题的动力学，将通过期刊出版物和会议演示广泛传播给研究界。

The research objective of this award is to investigate and simulate the dynamic effects of coil wedge in sheet rolling and coiling operations using a new mixed finite element method. The research approach is to use a rapid, new mixed finite element model to predict the rolling mill deflection. Combining this novel method with coil winding models, industry data, and stochastic analysis will enable a thorough investigation of the coil wedge problem. The research effort will integrate the rapid new mixed finite element model with operating data and expertise of two mill manufacturers and a major metal producer.If successful, the benefits and broader impacts will include the ability to roll superior products with greater efficiency and reduced energy. The research results will directly benefit the producers of specialty flat-rolled metals and the manufacturers of specialty rolling mills. End users of higher quality, more efficiently-produced steel, aluminum, copper, and brass coils will also benefit from the research. Furthermore, the work will expose diverse student groups to metals manufacturing curricula and exciting metals industry research. Wright State will leverage its existing outreach programs to encourage women, minorities, and students with disabilities to conduct work in the metal rolling field, and prepare for enhanced career opportunities. The simulation results, which explain the dynamics of coil wedge problems, will be broadly disseminated to the research community through journal publications and conference presentations.
