The propagation equations of surface acoustic wave in the semi-infinite quartz crystal and infinite quartz crystal plate is established with consideration of gyroscopic effects.By numerical computation

the wave velocity-rotating frequency curves and wave velocity-rotating axis angle curves have been plotted.Numeric results show that with the increase of rotational frequency

the wave velocities we obtained decreased

and the gyroscopic effects caused by the rotating around the propagation direction of surface acoustic wave has obvious effect on the wave velocities.During surface acoustic wave propagating in the infinite quartz crystal plate with consideration of the effect of rotating fields

the two surface acoustic wave velocities obtained tend to that of semi-infinite quartz crystal with increase of plate thickness.In the actual surface acoustic wave gyroscopic effect sensor design

gyroscopic effect can be analyzed based on wave velocities

rotating frequency and rotating axis angle.
