Product Overview

It is used to provide temperature and humidity change environment for aerospace, aviation, aviation petroleum, chemicals, electronics, communications and other scientific research and production units. At the same time, the electrical vibration stress can be applied to the test sample according to the specified period in the test chamber for test the reliability and adaptively of the sample. The product introduction is divided into two parts, the first part is Electromagnetic Vibration Testing Machine SN553-EV322HG120VT120.GP.VCS-2,and the second part is Temperature, Humidity and Vibration Three Comprehensive Test Chamber SN888-7200B-CT.

Technical Parameters

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.
