在新型冲击微动磨损试验机上对四种常见材料的薄壁管(不锈钢、铜合金、纯钛和铝合金)进行了冲击磨损试验，考察了材料属性、冲击能量对薄壁管损伤行为的影响。对其冲击动力学行为、磨损行为进行了分析。研究结果表明，不同材料金属管的能量吸收率、冲击接触力和冲击管变形有显著差异;同一种材料，随着初始冲击动能的增大，冲击过程中接触力、冲击管变形和冲击吸收能也在增大。通过分析磨痕微观形貌和磨痕轮廓，发现薄壁管的冲击磨损抵抗性能与材料属性密切相关;随着初始冲击动能的增加，材料损伤加剧，其损伤机制为疲劳磨损。

：The micro-amplitude impact wear tests of four types of common thin-walled tube materials(stainless steel,brass alloy,pure titanium and aluminum alloy)are conducted under a low-energy impact fretting wear tester .The impact dynamics behavior and damage behavior of the tubes is inspect during the impact fretting wear progress. The results show that there are significant difference of different materials tube in terms of energy absorption rate,contact force and tube deformation. For the same material,with the initial kinetic impact energy increased,the impact contact force,tube deformation displacement and impact absorption energy also increased. Through analyzing the morphologies and profiles of the wear scars,it indicates that impact wear resistance is related to impact dynamics behavior and properties of the test materials. With the increase of kinetic impact energy,the damage became servers,and the damage mechanism of thin-wall tube is fatigue wear.
