Vibrating Beam Accelerometers SpringerLink
Their underlying physical principle is that the transverse resonant frequency of a string or bar depends on the tensile stress, and the stress can be made a function of acceleration by fixing a proof mass to the string or bar. We will examine the design of two versions of vibrating beam accelerometers (VBAs) and describe their performance models.

Vibrating beam accelerometer - Sundstrand Data
For a single beam force sensing element, one suitable vibration mode is a flexural mode in which the beam vibrates from side-to-side in a direction normal to the accelerometer's sensitive axis and normal to the lengthwise pendulum axis, i.e., the pendulum axis extending between the end connected to the flexure hinge and the end connected to the force sensing element.

Vibrating Beam Accelerometer with Hard Suspension
This report provides a bulk-micromachined vibratory beam accelerometer. The device structure includes a frame, heavy mass, thick suspension beams and thin vibrating beams. The suspension beams are designed to be soft to the sensitive axis and hard to the off-axis. This brings about low off-axis sensitivity and high shock survivability. Combining with analog/digital mixed interface circuitry ...
