摘　　要：在室温下的空气和水中实验研究了激励力幅比、激励力幅值、激励频率、支承间隙和支承板厚度对传热管碰撞力和磨损率的影响,建立了微振磨损率与碰撞力均方根值之间的实验关系式。This paper presents some information about impact force and frettingwear by performing a series of tests with various parameters:ratio of ex-citation force components,amplitude and frequency of excitation force,tube to support plate clearance and support plate thickness.Tests are con-ducted in air and water,at room temperature.Finally,an experimentalcorrelation of wear rate and root-mean-square of impact force has beenabtained.
