Source Identifiers
In the previous paper, the transmission-radiation coefficient of combustion noise was proposed in order to investigate the engine structure response from the viewpoint of combustion noise generation. In this paper, the coefficients were examined for both a non-running engine structure excited by single explosion and an operated one. Using the vibration isolation techniques, the characteristics of these coefficients were obtained for three transmission paths of the test engine structure. The experimental methods to clarify the generation mechanisms of combustion noise were also discussed.
