摘要：

The new translational/angular accelerometer presented in this paper consists of a pair of identical piezoelectric cantilever beams inside a metal housing. Integrated hybrid charge amplifiers convert the piezoelectric charge signals to high level, low impedance voltages. The sensor is easily mounted on the surface of the structure under test by fixing it with wax or glue. It allows the simultaneous measurement of translational and angular acceleration. An example of an estimation of the frequency response function of a free-free beam is presented. © 1990.
