Test Environment Design for Acoustic Transducer Dynamic Calibration
Jia Shu-shi · Machine Tool & Hydraulics · 2003
To calibrate acoustic transducer well and truly, an acoustics and vibration multiple environments is necessary. This paper presented a test environment design of acoustic transducer dynamic calibration under the acoustic and vibration environment,and general idea of the whole dynamic calibration system was given,the design emphasis of every part of the test environment was studied. The design of level vibration table,the key equipment of this calibration system,was presented concretely.For the especial environment of the study,Sine vibration test and random vibration test were provided with corresponding analysis. The design was good reference in testing acoustics and vibration characteristics under even more complicated environment.
