CAREER: Dynamically Adaptive Feed Drive Systems for Smart and Sustainable Manufacturing

该学院早期职业发展（CAREER）计划奖的目的是研究将“快速变化的动态”引入进给驱动器及其协同开发，以同时实现高速度，高精度和降低精密制造机器的能耗/成本。进给驱动器（即，运动传递系统）目前被保守地设计成具有固定的机电结构，导致在速度、精度和能量效率之间的不期望的折衷。该研究设想饲料驱动器的设计像混合动力电动汽车的动力总成;它想象他们的设计是智能地改变他们的机电结构在真实的时间，以实现高性能和能源效率作为一个功能的制造操作正在执行。这些所谓的动态自适应进给驱动器的关键挑战是，它们需要一种用于产生最佳组合动态的设计方法（即，最大化协同作用）。在文献中没有这样的方法。这项研究的智力价值在于解决这一知识差距，从而使动态自适应系统的好处得到充分利用。教育目标是通过课程开发和外展工作，促进工程教育中的协同思维，从而有助于培养更多样化和更有能力的劳动力。这项研究的更广泛影响是在不过度牺牲质量和生产力的情况下，使各种制造机器的能源效率得到显着改善-类似于混合动力汽车在汽车行业的变革性影响。与美国工业合作伙伴的合作将使这项研究的成果能够转移到工业中。 该教育计划将开发教学资源，以解决本科教育条块分割的问题，并开展非传统的外联工作，通过在学科的社会文化背景下介绍科学/工程职业，激励代表性不足的中学生追求科学/工程职业。

The objective of this Faculty Early Career Development (CAREER) Program award is to investigate the introduction of "fast-varying dynamics" into feed drives and its synergistic exploitation as a means to simultaneously achieve high speed, high accuracy and reduced energy consumption/costs in precision manufacturing machines. Feed drives (i.e., motion delivery systems) of manufacturing machines are currently designed conservatively with fixed electromechanical structures, resulting in undesirable compromises among speed, accuracy and energy efficiency. The research imagines feed drives designed like the powertrains of hybrid electric vehicles; it imagines that they are designed to intelligently vary their electromechanical structure in real time to achieve high performance and energy efficiency as a function of the manufacturing operation being performed. The key challenge with these so-called dynamically adaptive feed drives is that they require a design approach for generating the best combined dynamics (i.e., maximizing synergy) under fast switching. No such approach is available in the literature. The intellectual merit of this research is in addressing this knowledge gap thus enabling the benefits of dynamically adaptive systems to be fully exploited. The educational objective is to foster synergistic thinking in engineering education through curriculum development and outreach efforts that contribute to a more diverse and capable workforce.The broader impact of this research is in enabling significant improvements in the energy efficiency of a wide range of manufacturing machines without unduly sacrificing their quality and productivity - similar to the transformative impact of hybrid electric vehicles in the automotive sector. Collaborations with a US-based industrial partner will enable the results of this research to be transferred to industry. The educational plan will develop teaching resources to address the problem of compartmentalized undergraduate education, and pursue an unconventional outreach effort that inspires underrepresented middle school students towards pursuing science/engineering careers by presenting science/engineering careers in the socio-cultural context of the subjects.
