Figure 8 : Instrumentation of the test, a) Accelerometer C33, b) Accelerometer C34. a) Signal conditioner. b) Impact hammer. Figure 9 : Instrumentation of the test, a) Signal conditioner, b) Impact hammer. a) Simply supported beam. b) Data acquisition system. Figure 10 : General view of the test system, a) Simply supported beam, b) Data acquisition system. Figure 11 : Position of the accelerometers. Discretization of the beam The discretization of the beam is important for the positioning control of the additional mass along the beam. A spacing “s” of 20 cm for both Cases (Case-1 and Case-2), as can be seen in Fig. 12 is considered.
