| Abstract: | The concept of shock response spectrum (SRS) and the classification and principle of related test equipments are introduced. A calibration method of the test equipment is proposed according to a current verification regulation of shock test machine. A novel calibration apparatus for the SRS test equipment based on virtual instrumentation technique is designed, and the simulation results of SRS for some typical shock waves (half-sine wave, rectangular wave, peak sawtooth pulse) are provided for verification. The results are completely in accordance with the theoretical ones, which proves the reliability of the algorithm being used and the calibration ability for the SRS test equipment. |
