Random vibration testing provides energy simultaneously at all frequencies. Vibration testing can help ensure that your new design will survive its intended environment. The problem is knowing how ...

Many readers probably think “black magic” describes the math involved in finding the dynamic response of a structure from random excitation. When can you be sure you have jumped through all the ...

Many shaker controllers for random vibration testing are based on the well-established FFT data processing algorithm. A test specification is given in the frequency domain in terms of power spectral ...

NOTE: Click on images or equations to make them larger. Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced ...
