A vibration controller feature within a closed-loop test system for replicating a waveform with precise, real-time, multi-channel control.
Time waveform replication (TWR), also known as long time history (LTH), exactly replicates, in the laboratory, vibration environments using data obtained in the field. Field measurements, such as a vehicle’s road test or an aircraft flight run, can be imported into the host PC, compensated for suitability to the shaker system, and then used to re-create the field environment within the laboratory.
