Because most systems and structures can be characterized by SDOF systems, even complex equipment or structures can also use dominant frequency (that is, the frequency corresponding to the maximum value on the spectral density curve) or analog frequency (that is, how many cycles per second, unit Hz), so the shock response spectrum can be used to easily determine the response peak of the structure under shock, and draw a conclusion whether it will be damaged; <br> <br>2) For statistical analysis of shock events, a reliable specification spectrum representing the shock environment can be obtained; <br> <br>3) Used for equivalent conversion of different shock waveforms, such as converting actual complex shocks into half-sine pulses with equivalent damage potential; <br> <br>4) Used for test validity and repeatability check; <br> <br>5) It is used to guide the design of shock-bearing systems. <br> <br>For more information about reliability test equipment, please feel free to contact us!
