| Abstract: | The rising edge of the shock wave signals requires the dynamic testing system has higher demands, especially for the sensors. This paper gets the mathematical models based on many shock wave tube calibration simulation experiments on the explosion overpressure measuring system.Moreover, it analyzes the dynamic compensated digital filter and the nonlinear compensation and correction methods ,where the transducer is the key factor.Simulation results show that the former method could shorten the dynamic respon... |
