The United States Patent & Trademark Office awarded U.S. Patent No. 11,287,351 B2 for Vibration Visualization with Real-Time and Interpolation Features to Dr. James Zhuge (CEO), Dr. Jeff Zhao (Senior Product Manager), and Aakash Umesh Mange (Senior Application Engineer) on March 29, 2022.
The invention patent outlines a workflow for visualizing real-time and offline vibration data using innovative features like interpolation and 3D reconstruction. This process effectively simplifies the interpretation of mathematical data and the geometry creation procedure. This novel approach is considerably helpful in fine-tuning the test setup to improve the measurement process.
A vibration testing system for structures visually displays vibration analysis information in the form of a graphic animation using a 3D model of the object. While only a subset of the object model’s surface points corresponds to sensors on the structure, an interpolation feature provided by the system allows deformation information from all points of the model to be estimated. Interpolation weights can be calculated in advance to provide a real-time display of a test. Color can be used to enhance the visualization of vibration amplitudes.
Users can implement the visualization feature offline after completing a vibration test to display the modal analysis results. Visualization can also be implemented in real-time using blocks or RMS data obtained during the vibration test. This option is especially useful for adjusting test parameters such as the excitation location, amplitude, or both, to achieve more effective testing.
