Modeling and performance study of a novel cross-node support structure of free-free beam vibration gyroscope
Analyzing performance of the free-free beam vibration,a novel cross-node support structure of free-free beam vibration gyroscope (CNSG) is proposed.In this paper,CNSG mathematical model has been established and dynamics equation has been deduced.To compare performance of two-node support structure of free-free beam vibration gyroscope (TNSG) through ANSYS software and relative theoretical calculation.The result indicates that CNSGs sensitivity has reduced by 10.738%,but shock resistance has increase by 94.44%,interference resistance frequency has increase by 66.02% and the cross-coupling error between the drive surface and the sensitive surface has reduced by 12.759%.Thus it gives a rational design of the support structure and provides a guideline on CNSG in complex application environment.
