| 摘 要： | 通过建立界面摩擦系统动力学模型,并利用原子力显微镜测试云母、石英以及单晶硅片界面摩擦条件下的黏滑行为特征,探讨摩擦系统内外因素对黏滑频率、幅值的影响。结果表明:同一实验条件下,不同材料的黏滑频率与黏滑波动幅值不同;缓慢滑动时,黏滑的频率主要取决于表面势场的频率,波动幅值取决于表面势场强度,随着滑动速度逐渐增大,黏滑频率同时取决于表面势场频率和探针系统的固有频率,波动幅值取决于表面势场强度和探针系统结构;滑动速度较大时,黏滑频率及波动幅值主要取决于探针系统,且随着滑动速度增大,波动幅值逐渐减小。

| Abstract: | By establishing interfacial friction dynamic model,and using the atomic force microscope to test the stick-slip friction behavier of mica,quartz and silicon chips under interfacial friction,the infulence of friction system external factors was explored.The results show that the stick-slip frequency and amplitude are different from the mtaerials under the same experimental condition.The stick-slip frequency depends mainly on the frequency of surface potential field,and the stick-slip amplitude on the potenti... |
