9731221 Bryant This award provides funds to permit Dr. Michael D. Bryant, Mechanical Engineering Department, University of Texas at Austin, to pursue with Dr. Chung Kyun Kim, Department of Mechanical Engineering, Hongik University, Seoul, Korea, for 36 months, a program of cooperative research on improving friction brakes by eliminating tribological problems and reducing wear. The collaborators will seek to improve high speed brake systems through complementary efforts, with each researcher working to improve different aspects of disc brakes, later to be combined. The combined effort could result in efficient, long lasting brakes on high speed trains, airplanes, automobiles, and industrial machinery Dr. Kim will contribute a new disc design and will analyze nonlinear thermal behavior of the disc and brake pad system using the Finite Element Method. He will redesign materials and geometry on the disc to optimize removal of heat and minimize thermal expansion problems that lead to brake noise and premature brake wear. Dr. Bryant will contribute new brake pad and disc designs that incorporate patented techniques that reduce brake pad wear and extend (double) life. Cooperative research issues will focus on problems that arise when combining the two designs: (1) necessary redesigns of both systems, (2) solving any problems that would prevent the two systems from functioning in a combined manner, (3) extensive testing of the new brake system, and (4) technology transfer to industries in both countries. Doubling brake life and eliminating other tribological brake problems could save both societies billions of dollars. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mut ual benefit. This project provides an international research experience for a U.S. graduate student. It also will add an international cooperative dimension to ongoing research under NSF Grant No. CMS-9713942, supported under the Surface Engineering and Tribology Program. Korean participation is supported by the Korea Science and Engineering Foundation (KOSEF). ***

9731221 Bryant 该奖项提供资金，允许德克萨斯大学奥斯汀分校机械工程系 Michael D. Bryant 博士与韩国首尔弘益大学机械工程系 Chung Kyun Kim 博士一起攻读 36 个月，一项通过消除摩擦学问题和减少磨损来改进摩擦制动器的合作研究计划。 合作者将寻求通过互补的努力来改进高速制动系统，每个研究人员都致力于改进盘式制动器的不同方面，然后将其合并。 共同努力可以为高速火车、飞机、汽车和工业机械带来高效、持久的制动器。Kim 博士将贡献一种新的制动盘设计，并将使用有限元方法分析制动盘和制动片系统的非线性热行为。 他将重新设计制动盘上的材料和几何形状，以优化散热并最大限度地减少导致制动噪音和制动过早磨损的热膨胀问题。 布莱恩特博士将贡献新的刹车片和刹车盘设计，其中采用了减少刹车片磨损并延长（双倍）寿命的专利技术。 合作研究问题将集中于组合两种设计时出现的问题：(1) 对两个系统进行必要的重新设计，(2) 解决任何妨碍两个系统以组合方式运行的问题，(3) 对系统进行广泛测试。新的制动系统，以及（4）向两国工业进行技术转让。 将制动器寿命加倍并消除其他摩擦学制动器问题可以为两个社会节省数十亿美元。 该项目与美韩合作科学计划的目标相关，该计划旨在通过科学信息、思想、技能和技术的交流以及在多种问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。双方的利益。 该项目为美国研究生提供国际研究经验。 它还将为正在进行的 NSF 拨款号 CMS-9713942 的研究增加国际合作的维度，并得到表面工程和摩擦学计划的支持。 韩国的参与得到了韩国科学与工程基金会（KOSEF）的支持。 ***
