摘要

为实现均匀辐照,ICF靶的无接触支撑是关键。提出用近场声悬浮对ICF靶进行无接触支撑,对悬浮ICF靶丸类微球的压电换能器和悬浮系统进行了初步设计,换能器发射端采用了凹球面结构,利用ANSYS软件对发射端的凹球面结构进行了优化。并构建了近场声悬浮测试系统,对不同直径的钢球在不同工作电压下进行了悬浮实验。实验结果表明:当发射端凹球面直径与钢球直径接近或相等时,悬浮效果是最好的,并且用气动的方式可以实现悬浮钢球的非接触驱动。当工作电压为600V时,钢球的悬浮高度为50μm,扰动振幅为3μm,这说明ICF靶近场声悬浮是可行的。

Abstract

For uniform irradiation in ICF, a non-contact target is the key technology. The method that ICF target is levitated by near-field acoustic levitation system is put forward. The transducer and the levitation system for ICF target are preliminary designed. The radiating surface of the transducer is concave spherical which is optimized by ANSYS software. The near-field acoustic levitation system is structured and different ICF target-like spheres are levitated in different voltages. When the diameters of the concave sphere surface and the ICF target-like sphere are similar or the same, the levitating effect is the best. Airflow can be used to drive the levitated sphere rotating non-contact. The levitating height is 50μm and the vibrating amplitude is 3μm when the driving voltage is 600V. It is feasible for ICF target levitated by near-field acoustic levitation system.
