Vibration Test Controller And Software For Sine , Random ,Classic Shock Test , RSTD , Sine With Resonant Search & Dwell
Vibration controller and software refer to the devices and programs used for controlling and analyzing vibration, which are widely applied in fields like aerospace, mechanical engineering, and vehicle engineering. The following is a detailed introduction:
- Working Principle1: Generally based on the PXIe bus structure, it adopts multi - DSP parallel processing technology and distributed modular design. Through advanced algorithms such as matrix decoupling and diagonal - priority matrix compensation, combined with technologies like closed - loop inspection and system identification, it realizes the control of vibration signals.
- Features1
- High Adaptability: The modular design can build the required test and analysis system by flexibly matching different data acquisition cards and output cards.
- Real - time Performance: The embedded PXIe control real - time computing system and real - time operating system, combined with multi - DSP parallel processing and high - speed transmission, can record data and analyze signals in real - time.
- High Precision: The 32 - bit floating - point DSP of each board card, 24 - bit resolution ADC, and low - noise design process ensure high - precision control.
Random vibration is used to closely approximate real world application environments. A wide range of frequencies are excited simultaneously at closely controlled energy levels. There are many examples of random vibration profiles which plot power spectral density (in units of g2/Hz) vs. frequency. Test specifications with frequencies up to and greater than 2,000Hz are considered broad band.Random vibration test specifications with upper frequencies less than 500 Hz are referred to as narrow band. Full system force is not achievable for narrow band, and the performance must be derated to protect the equipment.One very popular random vibration test specification is NAVMAT P9492 called out in the Navy Manufacturing Screening Program. This spectrum slopes up from 20 to 80 Hz at +3dB/octave to 0.04 g2/Hz, remains flat at 0.04 g2/Hz from 80 to 350 Hz, and rolls off at -3dB/octave from 350 to 2000 Hz. The overall grms value for this profile is 6.0 grms.
Sine with Resonant Search & Dwell
During sine testing, energy is out put at a single frequency. A sine sweep test is a useful engineering development technique which is
performed as a means to locate the resonance of a product. The resonance, or natural frequency, is the point where small vibration levels
cause the system to exhibit high amplitude levels. Dwelling at the resonance point is a common practice to determine if a product can
withstand a higher level of stress. Sine vibration performance for electrodynamic shakers is dictated by a curve which is limited by
