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.

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薄板轧制和卷取操作中的动态效果。研究方法是使用一种快速的、新的混合有限元模型来预测轧钢机的变形。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，将使彻底调查线圈楔形问题成为可能。这项研究工作将把快速新的混合有限元模型与两家磨机制造商和一家主要金属生产商的运营数据和专业知识相结合。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源轧制优质产品。研究成果将直接惠及特种扁轧金属生产商和特种轧钢机制造商。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这项研究中受益。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行业研究。莱特州立大学将利用其现有的外展计划，鼓励妇女、少数族裔和残疾学生在金属轧制领域开展工作，并为更多的职业机会做准备。模拟结果解释了线圈楔形问题的动态，将通过期刊出版物和会议演示广泛传播给研究界。
