Abstract
Major emphasis on the use of lightweight components in engines has lead to widespread use of polymer intake manifolds. The pulsed flow through these manifolds combined with the lower elastic modulus materials can result in excessive noise under certain speed load conditions. Using full-field optical techniques allowed for the detection and analysis of the resonance behavior in polymer intake manifolds. The test procedures involved techniques including time-averaged holography, with variable excitation sources to identify resonating regions and associated critical frequencies. The results clearly indicate the development of an efficient test methodology to analyze manifold designs for resonance and structural characteristics
