Abstract

The article presents a procedure which combines multiple-input modeling techniques and experimental modal analysis to develop control strategies for structurally generated noise. Multiple input models are used to rank the noise contributions from individual coherent structural members. From this ranking, frequencies associated with important sound radiating modes can be distinguished from inefficient modes. An experimental modal analysis focusing on the significant radiating frequencies enables visualization of the important noise generating modes. The results of the modal analysis indicate that a longitudinal vibration mode is the dominant radiating mode of the ram. This result is corroborated by an experimental shrouding study.
