Typically ESA's shaker tables are used to replicate the take-off vibrations of a satellite-lifting rocket. The large object seen here is not a satellite at all but an 8-tonne cooling system being ...
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 ...
Engineering researchers have developed a novel dynamic testing system for characterizing and evaluating the structural condition of short- to medium-span bridges – structures up to 300 feet long.
