中文摘要：

提出了一种超声无触点支承方案，详细介绍了超声无触点支承原理。通过对声辐射理论的研究，获得超声无触点支承的理论依据。实验证明实现这种超声波无触点支承是可行的。根据这一理论，对三轴无触点支承结构进行了选择设计。

英文摘要：

A project of ultrasonic contactless support is put forward, and its principle is detailed introduced. The theory basis of ultrasonic contactless support is achieved by studying the sound radiant theory. According the sound radiant theory, we choose the contractless support structure by experimentation. Experimentation validates that this ultrasonic contractless support scheme is viable.
