9713942 Bryant Initial studies have shown that micro-vibrations properly applied to bodies in sliding contact can reduce their wear by 50% or more. In this follow-up study the basic mechanisms involved will be studied and techniques will be developed to optimize the effect using passively generated vibrations for several target technologies, including automotive and aircraft brakes as well as electrical brushes. It is expected that near the end of the study subtle design changes can eventually be developed for automotive brake systems which will enable passive generation of vibrations that promote the vibration-induced wear reduction without having any deleterious side effects and that this could result in a very significant drop in brake wear. ***

9713942 Bryant最初的研究表明，在滑动接触中适当地施加到物体上的微振动可以减少50%或更多的磨损。 在这项后续研究中，将研究所涉及的基本机制，并将开发技术，以优化使用被动产生的振动对几个目标技术的影响，包括汽车和飞机制动器以及电刷。 预计在研究接近尾声时，最终可以为汽车制动系统开发出细微的设计变化，这将使被动产生振动，促进振动引起的磨损减少，而不会产生任何有害的副作用，这可能导致制动磨损的显著下降。 ***
