Vibrating Beam Accelerometer

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
