摘要：
An ultrasonication system for cells disruption is developed to extract nucleic acid from cells. The structure and operating principle of the ultrasonication system are explained, after which the key problems are stated. Based on finite element modal analysis, the top-ten natural frequencies of the round-shaped vibrating diaphragm are found having a character of stepped distribution, which can be divided into three grades. To optimize the vibration performance of vibrating diaphragm, simulation based on ANSYS is performed, the results of which show that medium grade frequency decreases with the increase of diameter while increases linearly with the increase of thickness.
