模拟涉及粘滑摩擦转换的瞬态接触问题

Boys 👑 on Instagram: "This video demonstrates the intersection of mechanical friction and acoustic resonance during industrial maintenance. The Subject The demonstration features a technician using a socket wrench to remove an oil drain plug from a large piece of heavy machinery. The Mechanism As the metal plug is unscrewed, the friction between the threaded surfaces creates high-frequency stick-slip vibrations. These mechanical oscillations are amplified by the hollow metal housing of the mach
