Web Seminar: Multi Frequency Swept Sine Vibration Testing

Multi Frequency Swept Sine Vibration Testing Thursday, February 12, 2015. 10am (Pacific Time, USA). Tom Villano, Senior Applications Engineer, will present the web seminar. Durability testing of engine mounted components is often performed using swept sine testing. This involves repeated sweeps of sine vibration across the frequency range of the engine vibration. This can be very costly and time consuming. A consortium of German automobile manufacturers approved the use of multiple simultaneous swept sine tones to reduce the time and cost of durability testing of engine mounted components. This web seminar will cover a multi frequency sine control technique that uses multiple swept sine control loops with independent digital tracking filters. The primary advantage of this technique is that it significantly reduces the required test duration. The result is a system capable of smooth continuous sine sweeps that excite all frequencies in the test range without sacrificing control performance. Tom Villano has over twenty-five years of experience in vibration test and analysis. His application expertise includes data acquisition, dynamic signal analysis, structural modal analysis, rotating machinery analysis, acoustic analysis and vibration control. His vibration control experience includes both single shaker and multi shaker testing.
