Impulse Force Calibration with Dropped Weight and Laser Vibrometer

• Abstract:

  One impulse force device is set up in CIMM to calibrate force transducers’ sensitivities with dynamic method. The free falling weight impacts the calibrated force transducer to generate large-amplitude impulse force up to 200 kN with (1~10) ms pulse duration, and one extra small inertia mass is installed on the top of the falling mass to generate small impulse force down to 20 N. The impulse force is measured by laser interferometer to trace the force to mass, time and length. Several piezoelectric transducers are calibrated with the impulse force calibration device and the amplitude sensitivity’s measurement repeatability is below 0.4 %.
