9619527 Barber The author's previous eigenvalue solutions for the problem of thermoelastic distortions due to frictional contact heating will be extended to the general case where the perturbations are moving in the direction of sliding. This is relevant, for example, to the thermoelastic buckling and general performance of components such as automotive caliper brakes and automatic transmission clutches. The analytical studies and FEM solutions will be validated and supplemented with input from industrial collaborators, one an automotive brake laboratory and the other a manufacturer of automatic transmissions. The industrial input will be partly in the form of test data and partly as knowledge transfer obtained by having the two students who do their theses on the project spend their summers as interns at the respective industrial sites. ***

9619527 Barber作者之前针对摩擦接触加热引起的热弹性变形问题的特征值解将扩展到扰动沿滑动方向移动的一般情况。 例如，这与热弹性屈曲和诸如汽车卡钳制动器和自动变速器离合器的部件的一般性能有关。 分析研究和FEM解决方案将通过工业合作者的输入进行验证和补充，其中一个是汽车制动实验室，另一个是自动变速器制造商。 工业投入将部分以测试数据的形式出现，部分以知识转移的形式出现，这是通过让两名就该项目撰写论文的学生在各自的工业现场实习来实现的。 ***
