摘要
声表面波(SAW)器件具有无源、无线、微型、抗冲击力强,灵敏度高等优点。用它制作角速率传感器——SAW陀螺已成为研究热点。概述了SAW陀螺的应用及发展;着重分析了SAW陀螺两种结构模式的工作原理;指出SAW陀螺设计的关键是如何得到合适的参考振动速度,而使其省掉悬浮振动机构成为简单的单平面结构;提出了亟待研究解决的几个问题。
Surface acoustic wave device has outstanding advantages such as passive,wireless, miniature, high resistibility with impact, high sensitivity, etc. The SAW angular rate sensor (SAW gyroscope) has already become the focus under study.This paper sums up the application and development of SAW gyroscope,putting more emphasis on the operation principle of two kinds of structure modes of SAW gyroscope.The key problem of SAW gyroscope design is how to obtain the speed of vibration is pointed out,so that it can eliminate the suspending part,nary vibratory micro-gyroscope,and becomes simple plane structure accordingly.Finally several problems that and solved are proposed in this paper.
