“…According to the Archard wear theory, 19 which considers both the micro‐cutting and indentation mechanism, abrasive wear is primarily caused by abrasive particles. Those particles are partially pressed into the material surface by the external pressure, causing the groove‐like wear of the contact surface.…”

Significant load fluctuations are encountered when cutting the coal rock using the shearer spiral drum, causing excessive drum wear. Thus, a coupling discrete element model of coal‐rock was developed, and the discrete element method and multi‐body dynamics were used to build a two‐way coupling simulation model of coal rock drum cutting. The drum wear was analyzed, along with the pick and spiral blade wear positions. The results have shown that the pick wear is primarily concentrated at the pick tip and the shaft shoulder, while the outer spiral blade edge blade is generally worn near the pick root. The maximum wear depth obtained in the simulation was 0.00316 mm. The tangential cumulative energy of the drum and the normal cumulative energy were 1.794e5 and 7.819e4 J, respectively. The friction wear of the drum was more prominent compared to the impact wear. By using a single factor method, the relationship between the drum rotational speed, traction speed, rock firmness coefficient, cutting depth, and spiral blade angle, and drum wear was obtained. Finally, it was concluded that the study at hand provides a quick and straightforward way to study drum wear law.

Fretting wear is a major form of fretting damage involving various factors, such as material properties, surface roughness, surface topography, lubrication conditions, environment temperature, type of loading, and loading phase difference. In this study, ABAQUS is used to establish three models to simulate the variation of wear depth with the amplitude of additional load. The influence of the phase difference between additional load and original load is considered. Four phase difference angles are involved, i.e. 0°, 90°, 180°, and 270°. Results indicate that the rule of the variation of wear depth with the additional load amplitude increasing varies under different phase differences. It is observed that for the 0° phase difference, the wear depth firstly decreases then increases with the increase of the additional load. However, the wear depth increases monotonously in the case of the 180° phase difference. The variation of wear depth with additional load amplitude for 90° phase difference is similar to that of the 270° phase difference. The depth of wear is firstly kept at a relatively low level and then increases sharply, with the increase of the additional load. It is found that the distribution of shear stress and relative slip at the contact interface is also affected by the phase difference.

The mechanisms and applications of friction energy dissipation

About 30% of the world’s primary energy consumption is in friction. The economic losses caused by friction energy dissipation and wear account for about 2%–7% of its gross domestic product (GDP) for different countries every year. The key to reducing energy consumption is to control the way of energy dissipation in the friction process. However, due to many various factors affecting friction and the lack of efficient detection methods, the energy dissipation mechanism in friction is still a challenging problem. Here, we firstly introduce the classical microscopic mechanism of friction energy dissipation, including phonon dissipation, electron dissipation, and non-contact friction energy dissipation. Then, we attempt to summarize the ultrafast friction energy dissipation and introduce the high-resolution friction energy dissipation detection system, since the origin of friction energy dissipation is essentially related to the ultrafast dynamics of excited electrons and phonons. Finally, the application of friction energy dissipation in representative high-end equipment is discussed, and the potential economic saving is predicted.
