PLANAR ACOUSTIC WAVE EXCITED AIRCRAFT WALLBOARD VIBRATION APPARATUS UNDER FREE BOUNDARY AND USE METHOD THEREOF

摘要

A planar acoustic wave excited aircraft wallboard vibration apparatus under a free boundary, the apparatus comprising an auxiliary positioning device, an omnidirectional measuring device, an automatic adjusting and suspending device, a movable acoustic wave excitation device, and an auxiliary device. The auxiliary device supports other four devices and provides auxiliary functions of an experimental device; the automatic adjusting and suspending device suspends an aircraft wallboard (19) and adjusts the height of the aircraft wallboard (19) before the start of a vibration test; the movable acoustic wave excitation device is the vibration source of the vibration experimental device; the omnidirectional measuring device measures and collects data when the aircraft wallboard (19) vibrates; and the auxiliary positioning device ensures that the aircraft wallboard (19) can return to an original measuring point after each vibration process. The apparatus is applicable to measure the dynamic characteristics of various aircraft wallboards, is simple and efficient, and can provide accurate data. In addition, also provided is a use method of a planar acoustic wave excited aircraft wallboard vibration apparatus under a free boundary.
