System overview:

The core of the system is the virtual instrument technology based on PXI bus. By using timing, trigger equipment and the best LabVIEW visualization software development platform, the development process of complex system is simplified and accelerated. It is mainly used for vibration characteristic detection of various equipment and modal analysis of specific components.

Solution:

(1) Provide a variety of display graphics, including Bode diagram, Nyquist diagram, octave diagram, geometric model and XY diagram;

(2) Channel setting function: configure online setting function of multiple channels;

(3) Function switch: the analysis results of each module have been completed in the test process, and have been saved as analysis files, which need to be read directly;

(4) In the process of power spectrum analysis, various settings are added, such as average setting, window function, etc;

(5) Various flexible 2D / 3D, color chart display and report printing output, etc;

(6) Data interface function: support the import and export of ODBC format data;

(7) Test software and data post-processing: the original data of vibration and noise test can be extracted conveniently and quickly;

(8) The vibration and noise test data are vibration acceleration value and force sensor data of force hammer, and the original vibration acceleration and force sensor data waveform can be displayed in post-processing;

(9) Provide modal parameter identification function;

(10) Channel expandable: the number of current channels can be expanded according to user requirements;

(11) The signal type can be expanded: the current signal acquisition type can be expanded according to the user's demand;

(12) It supports the generation of various reports.

(13) Comparison and verification of the measurement results of the detection system and the third-party test results with the national test qualification: the deviation of the measurement results of all detection points is not more than 3dB, and the accuracy rate is as high as 90%.
