ANALYTICAL STUDY ON ENGINE VIBRATION TRANSFER CHARACTERISTICS USING SINGLE-SHOT COMBUSTION

To demonstrate the generation mechanism of combustion noise separately from mechanical noise, the process of transfer in which vibration travels to each engine portion was analyzed through single-shot combustion of a propane-air mixture in the combustion chamber with the crankshaft fixed at a given angle. The effect of the natural frequency of each portion of the engine on the vibration transfer characteristics is discussed by introducing a vibration transfer function. The transfer paths of existing forces which are caused by the combustion are quantitatively clarified.
