Abstract

Abstract

The frequency domain characteristics of measurement system are determined by transducer and secondary instrument, and the former one has been widely studied. It is shown that peak value, positive phase duration and impulse are affected by secondary instrument. The ideal shock wave signal was constructed for its frequency characteristic analysis. The low frequency characteristic of adapter was also experimentally investigated. Five different filters were modeled, and their output under different cutoff frequencies was simulated with the ideal shock wave as input signal. The simulation and experimental results are summarized as follows: The low frequency characteristic of adapter has the influence to positive phase duration and impulse; Bessel filter is the best one for shock wave measurement system of the five filters; The peak value of shock wave is obviously affected by the filters cutoff frequency; And the shock wave signal with short positive phase duration needs higher system bandwidth.
