| Summary: | In order to assess product’s ability to resist impact, shock tests should be made on rolling stock equipment of railway. However, classical shock such as half-sine shock couldnot simulate the actual impact environments effectively. With the development of computer technology and environmental simulation theory, shock response spectrum test could simulate the real impact of the system by environment more realistic. Firstly, shock response spectrum and classical shock pulses were compared. Then the physical model of shock response spectrum was subjected, as well as the shock response spectrum test principles. After that, a detailed description of time-domain waveform synthesis methods and optimization algorithms was presented. Finally, an example was taken to introduce SRS test processes, which provided support for the future SRS test. |
