This thesis intends to design a set of acoustics measurement system, it can
measure the rough surface to have the scattering influence regarding the sound
wave. And this set of acoustics measurement system will be able to provide
the rough surface establishment function, acoustics measurement precise pinpointing
for position and rough surface accurate shape data. Establishing the
main environment take the Institute of Undersea Technology large experiment
water tank as the system. The experiment water tank sets up XYZ table which
can control the three translation directions migration. Because this experiment
needs five degrees-of-freedom except for three translation directions migration
and also has two axes rotary motion. In order to measure scattering field so we
need to design the rotary mechanism for two axes that enables the microphone
to achieve themovements in five degrees-of-freedom.
In this experiment has to conformity themeasurement of laser system¡¦s rough
surface position, the position of microphone shooting and receiving point, and
establishes scraper position which rough surface used. In order to compare the
scattering state of the shape of rough surface and the soundwave beats the rough
surface after we integrate all the information, we can realize where directional
sound wave beats and what¡¦s the shape of this rough surface.
Except for conformity position, this equipment¡¦s localization is all by the programcontrolmotor.
It can save time in adjusting position for experimenter in an
effective way and itmay abridge the experiment time effectively.
