Device for laboratory testing of closed section for commercial aircraft cabins

摘要

Device for laboratory testing of closed section cars for commercial aircraft, with which an acoustic design and checking of the part of cabins, which in each case be taken into account as a relaxation room in the aircraft, is realized, in which a part of the elevator car (1) via a plurality of vibration exciters (4) for simulating a excitation body sound in the region of connecting elements (2) for connection to an aircraft - fuselage structure are taken into consideration, is arranged, whereby the part of the elevator car (1) various elements (5) for air sound excitation are assigned, characterized in that the vibration exciter (4) for the excitation body sound, which are each provided with a piezo - vibration exciters are realized, and the various elements (5) for air sound excitation, the with a loudspeaker arrangement and / or directly on the side walls of the part of the elevator car (1) arranged hall chambers are realized by means of control - and closed-loop control devices (6), the vibration exciters (4) and the various elements (5) are connected, can be set, and the control - and adjusting devices (6) a computing unit (7) is connected, which is supplied with signals from an input file (8) can be generated are.
