Digital vibration controller function description
Random control
According to the user-defined power spectrum diagram (made by the target spectrum editor), random control adopts the method of transfer function equalization. Continuously output Gaussian random signals to quickly implement real-time and accurate multi-channel closed-loop control. Built-in adaptive control algorithms react quickly to system nonlinearities, resonant frequency, and load changes.
Frequency range: 0~4800Hz, extendable to 18750Hz
Resolution: 100, 200, 400, 800, 1600, 3200 spectral lines
Control power range: >90dB
Control strategy: single channel control, weighted average, maximum value, minimum value.
Sine control
Sine provides analog-quality sine and sine sweep signals with control over the amplitude of the sine waveform. The dwell magnitude, dwell frequency can be set, and the dwell duration can be determined by setting the time or the number of cycles of the sinusoidal signal.
Frequency range: 1Hz~5000Hz, expandable to 10000Hz
Closed loop time: 5 mS
Harmonic distortion: <-100dB
Frequency sweep mode: linear frequency sweep 0~6000 Hz/min | Logarithmic sweep 0~100 Oct/min
Sweep direction: up, down
Sweep duration: can be set as the number of sweeps or test times.
Classical Shock
Adopt transfer function equalization method, support half sine wave, bell wave, rectangular wave, trapezoidal wave, front peak sawtooth wave, back peak sawtooth wave, triangular wave. Users can also input pulse peak value according to their needs.
Pulse duration from 0.5 to 3,000mS
Maximum analysis bandwidth 18750Hz
Frame size: up to 16384
Meet the standards: MIL-STD-810 (US military standard), ISO standard, user-defined interrupt control limit.
