Quartz rate sensors(QRS) made out of one single piece of quartz crystal are inertial devices which can be used for general rate control,stabilization,automotive and aerospace/defense markets,etc.The mechanical design of the QRS has been investigated based on axiomatic design.The axiomatic design matrix of the mechanical structure of Coriolis Vibratory Gyroscopes(CVG) has been proposed.The mechanical function of QRS is divided into three Function Requirements(FR),i.e.,FR1 is the drive mode,FR2 is the sense mode,FR3 is a coupled connection where the Coriolis force can couple the two modes with a term proportional to the rotational rate.A new QRS which is easy to be fabricated has been put forward.Furthermore,the new QRS indicated that the axiomatic design is a help to functional design of products.
