Research progress on engineering application and vibration control of Vibration Friction

Vibrational friction is an essential and complex dynamics problem in the field of engineering, which relates to the research of friction properties of contact surfaces between objects under vibrational situations. Vibrational friction can greatly change the friction and abrasion behavior between different objects, which can impact the dynamic behavior of equipment and mechanical life because of fatigue. With the performance requirements of machinery systems needing to be increased in modern industry, understanding vibratory friction is becoming more important. This article describes what vibrational friction is, why it happens, how it is affected, and how it is used in engineering practice. Some main things that affect vibratory friction are the speed and amplitude of vibration, the characteristics and surface roughness of the contact material together. Through analysis, it is found that moving stuff with those shaky machines or packing down soils can become cheaper and quicker thanks to vibratory friction, because vibratory friction can significantly improve efficiency and reduce energy loss. The potential engineering issues caused by vibration friction, such as fatigue failure and performance degradation of mechanical structures, as well as the occurrence of noise are discussed.
