چکیده انگلیسی


• A new dynamic friction coefficient testing setup was designed, which was modified from the split Hopkinson pressure bar.
• Time resolved dynamic friction coefficient can be tested under impacting loading.
• The geometry and stress state of tribo pairs are both simple.
• The dynamic friction coefficient can be directly calculated without any assumptions.
• The interfacial friction between two plastics and aluminum was tested.

We present a new dynamic friction coefficient testing device modified from the conventional split Hopkinson pressure bar (SHPB). In the experiment, the normal pressure and friction force are applied to the tribo pair simultaneously via the wedge structure of the incident bar. The geometry of tribo pairs can be cylindrical or cuboid which can be as simple as the samples in SHPB experiments, and the time-resolved interfacial friction coefficient can be directly calculated without any assumptions or theoretical derivation. The interfacial friction between two plastics and aluminum was tested by the novel setup, the normal pressure and friction force histories were measured, and the time-resolved dynamic friction coefficient was obtained.
