Few Issues When Measuring A High-G-Shock
MetadataShow full item record
This paper deals with effects which cause differences between real and measured mechanical shock, namely a high-pass filtering caused by a piezoelectric sensor and a charge amplifier and a resonance ripple caused by a piezoelectric sensor. The first effect can be suppressed by properly selected filtration which fits the application’s requirements. To suppress the second effect the sensor’s model needs to be found. In previous work this was done by two-sensor method, now the frequencies are estimated from the electrical parameters of the sensor. A 2-DOF model is used as it suits better for high-g-shocks. The method is able to suppress some ripple effects in the shock shape.
