Mechanical Shock Shape Calculation from Estimated Accelerometer Parameters
Original language description
Mechanical shocks are often measured by piezoelectric accelerometers. This sensor type causes shock shape changes because it is essentially an under-damped second order dynamic system, therefore it ﬁlters sharp edges of shocks and adds damped oscillations. Because of a signal change occurring on a sensor, it is hard to calculate correctly a shock parameters or a shock response spectrum. Yet both are essential parameters for device testing. Extracting a shock shape from measured data is very complicated due to a signal noise and inaccuracies in sensor dynamic parameters. In this paper, we present a new method of calculation of an original shock shape and of a sensor dynamic parameters when a mechanical shock is measured by two accelerometers with different frequency spectrum. New method was tested on simulated data and veriﬁed during experiment which provided overall accuracy up to 5 %.
