U.S.-Korea Cooperative Research on Improving Friction Brakes by Eliminating Tribological Problems and Reducing Wear

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的Michael D. Bryant博士与韩国首尔弘益大学机械工程系的Chung Kyun Kim博士进行为期36个月的合作研究项目，通过消除摩擦学问题和减少磨损来改进摩擦制动器。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，稍后将结合起来。双方的共同努力将为高速列车、飞机、汽车和工业机械提供高效、持久的制动器。Kim博士将提供一种新的制动盘设计，并将使用有限元方法分析制动盘和刹车片系统的非线性热行为。他将重新设计制动盘的材料和几何形状，以优化散热，并最大限度地减少导致刹车噪音和刹车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光盘设计，结合专利技术，减少刹车片磨损和延长（双倍）寿命。合作研究问题将集中在结合两种设计时出现的问题：(1)两个系统的必要重新设计，(2)解决任何可能阻止两个系统以组合方式运行的问题，(3)对新制动系统进行广泛测试，以及(4)向两国工业转移技术。将刹车寿命延长一倍，并消除其他刹车摩擦学问题，可以为两个社会节省数十亿美元。该项目与美韩合作科学项目的目标相关，该项目旨在通过交流科学信息、思想、技能和技术以及通过在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。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研究增加一个国际合作的维度。CMS-9713942，由表面工程和摩擦学项目支持。韩国的参与得到了韩国科学工程财团（KOSEF）的支持。＊＊＊

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). ***
