Multifunctional underwater acoustic parameter comprehensive test experimental device

Abstract

The invention discloses a multifunctional underwater acoustic parameter comprehensive test experimental device, which comprises an underwater acoustic tank, a tested transducer, a standard receiver, an auxiliary transmitting transducer, an reciprocal transducer, a rotary lifting mechanism, an electronic test equipment and a test software. The invention is a necessary experiment teaching instrumentequipment for the underwater acoustic engineering professional practice teaching courses. Various underwater sound field environments including low-frequency standing wave field, a medium-high-frequency free field, a reverberation field and the like can be simulated in a limited space in a laboratory under different frequency bands, so that underwater acoustics, underwater acoustic transducer, sonar and other professional theoretical knowledge can be verified. The invention specifically relates to a multifunctional underwater acoustic parameter comprehensive test experimental device which canrealize experiment teaching of basic parameters of underwater acoustics, underwater acoustic transducer and sonar basic parameters in a laboratory with a frequency range of 2-200 kHz.

Description

technical field [0001] The invention belongs to the field of experimental testing, and specifically relates to a multi-functional underwater acoustic device that can realize experimental teaching of basic parameters of underwater acoustics, underwater acoustic transducers and sonar in the laboratory within the frequency range of 2-200kHz. Parameter comprehensive test experimental device. Background technique [0002] In the field of underwater acoustics, the device for testing the basic parameters of underwater acoustics, underwater acoustic transducers and sonar mainly refers to the free field test system based on the test pool. The underwater acoustic experiment requires a free sound field environment, which can be realized through a large outdoor test field and an indoor anechoic pool. Compared with large outdoor waters, pool equipment has the advantages of suitable location and controllable environment, and in natural waters, due to the large background interference, it...

Problems solved by technology

In addition, in the field of underwater acoustic measurement, there are also measurement spaces such as water tanks (water tanks) and acoustic tubes (or coupling chambers). Among them, the former can only complete high-frequency measurement work; the latter can only complete low-frequency measurement work, and in these two Usually only sensitivity calibration of standard hydrophones can be done in space
