“…5; it is evident that there is no direct relationship between the wear and the coefficient of friction of the composite according to the composition ratio. Wang et al [36] investigated the effects of wear particles on the tangential acceleration in the stickslip oscillation environment of five different materials under the same external conditions. It was found that the wear particle called the third body, generated during the friction process, acts as a lubricant at the contact interface, reducing the stick-slip vibration that causes tangential acceleration.…”

The tribological performance and friction-induced vibration of Gd0.2-Ce0.8O1.9 (GDC) reinforced nickel oxide (NiO) metal matrix composites prepared via sintering on the tribological performance, as well as friction induced vibration were investigated. Compared to pure NiO, the composites exhibit improved mechanical properties, such as a relatively high dislocation density, hardness and small grain size. The results show that GDC-reinforced NiO nanocomposites feature improved tribological performance and can suppress the occurrence of friction-induced vibration under variable loading conditions. Furthermore, the generated acceleration can be suppressed by wear particles generated during the friction process, acting as the third body at the contact interface. As a result, the addition of GDC reduces the grain size of the composite, increases hardness, and improves tribological properties through the synergetic effect of the solid lubricating action of NiO and the role of the third body of the wear particle.

“…In general, stick−slip friction causes serious problems, including surface damage, noise, reduced equipment precision, and energy loss. 1−3 Research on stick−slip friction has been explored throughout a broad area from automobiles, 2,4−9 high-speed trains, 10,11 marine equipment, 12−15 and drilling systems. 16−18 In recent years, noise, vibration, and harshness (NVH) problems caused by stick−slip friction between the interior materials of automobiles have raised concerns from automotive original equipment manufacturers because these issues lead to uncomfortable and unhealthy experiences for customers.…”

“…19 Wear characteristics, such as detachment, wear debris, and plowing, also significantly influence the stick−slip friction owing contact change. [11][12][13]44 Studies analyzed R q in relation to the stick−slip friction during wear, and results indicated that R q shows a significant and systematic increase but no actual correlation with stick−slip friction. 32,45 The surface topography parameters that are most suitable for describing stick−slip behavior with various surface topographies observed during the wear process are rarely discussed in the literature.…”

This study examined the influence of worn surfaces on the stick−slip friction of galvanized automotive steel and revealed the intrinsic role of surface topography parameters in the stick−slip friction with wear. The results show that the surface deformation induced by wear significantly affects the stick−slip friction. The stick−slip friction can be suppressed by increasing the vertical area of the surface deformation because of reductions in the difference between the static and kinetic friction coefficients. The friction behavior changes from stick−slip friction to smooth sliding when the skewness exceeds a critical value, thus suggesting that this parameter can be used as an effective surface topography parameter to describe the stick−slip friction of galvanized automotive steel with worn surfaces. The findings can help improve the understanding of the mechanism of the stick−slip friction of materials with worn surfaces and provide an approach to suppress the noise and vibration caused by the stick−slip friction of galvanized automotive steel.

“…Dong et al [43] assessed the relationship between the polymer's lubrication performance and stick-slip and frictional noise; it was found that materials with better hydrophilicity, self-lubricity, and viscoelasticity produced less stick-slip and lower friction noise. Wang et al [44] experimentally analyzed the in uence of different damping alloys as friction pair materials on stick-slip vibration; the results showed that Mn-Cu damping alloys and aluminum alloys provided the best suppression of stick-slip oscillations. The study also revealed different wear behaviors and clari ed the correlation between different wear behaviors and the stick-slip oscillations.…”

In the experiment, we observed such a phenomenon: the alternating normal force changes the vibration state of a friction system. A single-degree-of-freedom mathematical model was used in this paper to discuss the effects of a constant and alternating normal force on the stick-slip vibration characteristics for different dynamic and static friction coe cients. Under the condition that the applied constant normal force continues to increase, the vibration amplitude of the system, the amplitude of the limit cycle, and the adhesion time of the system increase. When the difference between the dynamic and static friction coe cients (DSFC) is small, the system has a complete and clear limit cycle. When the dynamic friction coe cient is reduced, the difference between DSFC increases, and the limit cycle of the system is deformed. The friction system has more abundant dynamic vibration characteristics under an alternating normal force than a constant normal force. The vibration state of the system presents a single-cycle stick-slip vibration when the alternating normal force excites the multi-order harmonic response of the friction system, and the excitation frequency of the alternating normal force is the same as the main response frequency of the system with the highest energy or the low-order even-order main frequency. In contrast, the system exhibits various vibration modes when the excitation frequency of the alternating normal force is dissimilar to the main frequency of the system's highest energy response or is consistent with the odd-order main frequency. In addition, increasing the difference between DSFC or using very high excitation frequencies and excitation amplitudes increase the likelihood of the system entering a chaotic vibration state.
