Multiple-Input Multiple-Output (MIMO) Shock Control
The EDM MIMO VCS software suite now includes MIMO Shock control testing in addition to MIMO Random control, MIMO Sine control and MIMO Time Waveform Replication control testing. MIMO Shock control tests are used to measure the reliability and durability of an object under test.
The newly added MIMO Shock control is a type of multiple-shaker control testing, which provides precise, real-time, multi-channel control and analysis of classical shock waveforms in the time domain. The MIMO Shock control process is essentially a time-domain waveform replication process that uses an FFT based algorithm for correcting the test system dynamics.
A MIMO Shock test outputs a series of pulses to test the structure. The responses are measured at multiple locations on the structure and a spectral analysis is used to determine its frequency characteristics. The Fourier transform of the impulse response is the Frequency Response Function (FRF) of the system.
