Statistical evaluation of experimental and numerical data of stick–slip effects in harmonically excited systems

Novel Wood-Based Functional Material with Vibration and Noise Reduction

“…However, when the composites are in a harsh operating environment (long running and poor lubrication conditions), the friction force on the contact interface increases, and then frictional heat accumulates sharply, resulting in weakened tribological properties and significant deformation behaviors. 8−10 Uncertain system disturbances caused by the stick−slip phenomena 11 and deformation behavior 12 can additionally generate frictional vibration, while the vibration also radiates noise, which can greatly affect the safety of mechanical equipment, the concealment of the warship, and the personnel comfort. 13−15 In addition, based on the background of the dual carbon strategy, 16−18 many scholars have paid attention to studying nonpolluting composites with the advantages of environmentfriendliness, easy preparation, and simple post-treatment properties.…”

“…In various engineering fields such as aviation, automotive, ship, and machinery, composites with good wear resistance, stable chemical properties, easy preparation, and modification have been widely used in sealing components, water-lubricated bearings, and even artificial auxiliary organs, and their self-lubricating properties are unanimously recognized by worldwide researchers. However, when the composites are in a harsh operating environment (long running and poor lubrication conditions), the friction force on the contact interface increases, and then frictional heat accumulates sharply, resulting in weakened tribological properties and significant deformation behaviors. − Uncertain system disturbances caused by the stick–slip phenomena and deformation behavior can additionally generate frictional vibration, while the vibration also radiates noise, which can greatly affect the safety of mechanical equipment, the concealment of the warship, and the personnel comfort. − In addition, based on the background of the dual carbon strategy, − many scholars have paid attention to studying nonpolluting composites with the advantages of environment-friendliness, easy preparation, and simple post-treatment properties. Therefore, improving the vibration and noise reduction of natural materials under contact motion conditions is very promising for the future functional materials.…”
