2 buildings consisting of a 5-story building and a 2-story building were installed with sensitive machines, which fabricate the microelectronics components such as external hard drives. Those require a free-vibration condition. Thus, 70 locations of machine vibration were measured. In each location, vibration in all three axes including two horizontal directions (X, Y) and one […]
