DV3001 natural frequency analysis module can perform frequency response function analysis (FRF Analysis) on the tapping signal and vibration/acoustic signal in the modal experiment to obtain information such as the natural frequency and damping ratio of the component or structure. The DV3001 natural frequency analysis module automatically identifies the possible natural frequencies based on the amplitude, phase, and correlation in the frequency response function analysis results. The DV3001 Natural Frequency Analysis Module analyzes the tapping signals in modal experiments to help you assess the quality of the tapping signal. All analysis functions can be observed immediately in the experiment, and you can also use them on the post-processing stage.
Scenario
When you have the following analysis requirements, we recommend that you adopt the DV3001 Natural Frequency Analysis Module.
- Analyze the natural frequencies of components or structures.
- Avoid the possibility of resonance between the excitation source and the structure from design
- Filter products with internal and external casting defects in the production line
- Want to establish a structural dynamic test standard in the production line.
Case study
Product resonance characteristic detection.
- Perform a beating test on components such as automobile brake discs, calipers, steering knuckles, etc., and analyzing their resonance frequency and damping ratio to avoid the resonance noise of the brakes.
- Perform a tapping test on the steering knuckle of the car and analyze its resonance frequency to check whether there is a casting defect.
- perform Natural frequency analysis and detection of the servo casing to avoid resonance between the structure and the excitation source such as the cooling fan, thereby reducing the efficiency of hard disk reading.
- perform Natural frequency analysis and detection of machine tool spindles and other components.
