摘要： A vibratory angular rate sensing system may have one pair of tines forming an angle of about 60 degrees, resulting from the crystalline orientation of the Z-cut quartz wafer of the system. In one configuration each of the tines is provided with a mass offset from the axis of the associated tine, a pivot extends through the plane of symmetry of the tines and may be connected to a dummy reaction mass. The resonant system is suspended from a mounting frame by a pair of suspension bridges. A second embodiment of the invention features two groups of tines, each group including two pairs of tines arranged in the form of a cross. Again, an offset mass is associated with the free end of each tine and each group of tines is secured to its frame by a suspension bridge.

摘要： An angular rate sensor system is disclosed, consisting of a balanced resonant sensor. The sensor consists of a tuning fork of a piezoelectric material, preferably of quartz. The tines of the tuning fork are caused to vibrate electromechanically, for example, by impressing an alternating voltage on a pair of electrodes on each tine. This will cause the tines to vibrate. Any component of angular motion around the axis of the sensor causes a cyclic deflection of the tines at right angles to the normal driven vibration of the tines. If the rotational input to the handle of the sensor is applied through a torsion element, the resulting tine deflection is directed to cyclically rotate the entire sensor along the input/output axis. This deflection can be used for changing the capacitance of a capacitance bridge, or for generating an electric signal, due to the piezoelectric effect resulting from the deflection. Finally, the output signal may consist of a frequency-modulated signal or an optical pick-up may be used. The system may take various forms, including one, two, four, or eight tuning forks forming a unitary system.
摘要翻译：公开了一种由平衡谐振传感器组成的角速率传感器系统。传感器由压电材料的音叉组成，最好是石英。音叉的齿通过机械地振动，例如通过在每个齿上的一对电极上施加交流电压。这将导致尖齿振动。围绕传感器轴线的角运动的任何分量导致尖齿与尖齿的正常驱动振动成直角的循环偏转。如果通过扭转元件施加传感器手柄的旋转输入，则所得到的齿偏转被引导以使整个传感器沿输入/输出轴线循环旋转。由于偏转产生的压电效应，该偏转可以用于改变电容桥的电容或用于产生电信号。最后，输出信号可以由调频信号组成，也可以使用光学拾取器。该系统可以采取各种形式，包括形成单一系统的一个，两个，四个或八个调谐叉。
