CSVR 振動與噪音工程研究中心

  Early in the department, the research on high-performance ship technology was very important, and it was effective in the development of high-performance propulsion systems and the establishment of vibration and noise prevention technology. In addition to improving the efficiency of high-performance ships, the vibration noise derived from the high-powered main engine and propellers is an issue that needs to be overcome. Due to this demand, the department has recruited several professors with vibration and noise research expertise more than ten years ago. For many years, he has been engaged in the analysis and prevention of vibrations of machinery and implements, as well as air sounds, water sounds and structural sounds. In addition, there are several professors in the department who are engaged in ship vibration and structural vibration mechanics research, so human resources have begun to take foundation.
In addition to integrating the human resources engaged in vibration and noise research into a research team, the department has successively constructed structural vibration laboratory, full soundless laboratory, reverberation laboratory, MTS structural dynamic laboratory and retrofitting large cavitation tank. In the water, there is no sound room, etc. The equipment of these laboratories is perfect and has the scale of industrial application.

  The center was established in 1999 mainly consisting of medium-sized cavitation sinks and large cavitation sinks. The latter is the world's third-largest low-background noise sink, meeting military requirements and costing more than NT$360 million. The main research areas of the center are: (1) the flow field of underwater high-speed complex shape and its related research on fluid dynamics, (2) the cavitation of fluid machinery and marine propulsion and the sound pressure field induced by it. 3) Conduct research on the interaction between the hull and the propeller.
The medium-sized cavitation sink is one of the few sinks in the world that can measure the thrust, torque, lateral force and vertical force of the speedboat propeller operating under the oblique axis condition. The sink can also measure the counter-rotating snail. Vibration and noise caused by paddles and cavitation propellers.
