| Abstract: | The three dimensional vibration of Large dimension vibration systems by the coupled vibration theory are studied. The frequency equation for the design and calculation of systems is derived out theoretically. A new method of sloting in the suppressing of transverse vibration is developed, and the theoretical expression of sloting positions is given. Experiments show that the measured resonant frequencies agree well with the calculated results according to the theory, and sloting improves the uniformity of displacement distribution on the radiating surface of large dimension vibrating systems. |
