Modal testing involves collecting frequency response functions using either an impact or shaker excitation technique. Impact testing is often performed due to the ease of the test setup and simplicity of the measurement process. But larger structures may not be adequately excited with single impact excitation locations as the test progresses.
Read MoreThe EDM 12.1 release introduces Live Frequency-Domain Animation to help users visualize and interpret structural vibration data during testing. With this enhancement, users can now observe Operational Deflection Shapes (ODS) in real time while running Random, Sine, or other data acquisition or modal tests.
Read MoreModal analysis of a cantilevered plate was successfully performed using the Luma-600 laser vibrometer. The results align with expectations and confirm the effectiveness of the Luma-600 as a non-contact vibration measurement tool for accurate and efficient modal testing.
Read MoreTo ensure aircraft safety and flutter-free operation within safe flight envelopes, high-channel-count Ground Vibration Testing (GVT) systems are widely employed for structural analysis. These systems facilitate seamless data acquisition, analysis, and post-processing to assess the dynamic behavior of aircraft. However, traditional GVT approaches often involve extensive cabling, complex test setups, and time-intensive data processing, making them cumbersome and resource-intensive.
