Abstract

The interior noise of an excavator cabin is important factor related to operation efficiency. For analyzing the cabin air-borne sound, the SEA cabin model was developed using VA One. Analysis result using measured surface SPL of cabin was compared with test data. And the noise reduction guide of cabin was suggested with contribution and sensitivity analysis results of major design variables using developed SEA analysis.
