Characterization and Design of Quartz Rate Sensors
暂无分享,去创建一个
The BEI Systron Donner’s quartz rate sensor (QRS) uses double-ended quartz tuning fork to sense angular rate. The drive fork, acting as a Coriolis sensor, is coupled to a similar fork as a pickup to produce the rate output signal. In this paper, the theoretical analysis of the quartz fork model is presented. Following that, FEA analysis results are discussed. The consideration to optimize fork design is detailed. Experiments from mechanical testing and electrical testing are presented to show the improvement of the fork design.Copyright © 2005 by ASME
