Experimental research on the noise of an agricultural tractor hydrostatic power steering and control unit



Experimental research on the noise of an agricultural tractor hydrostatic power steering and control unit



Rivista di Ingegneria Agraria 15(3): 149-158



The noise characteristics of a commercially available unit driven by 3 external gear pumps were studied. Fourrier analysis on experimental noise measurements confirmed high frequency pulsation oil flow, with pressure cycle irregularity being the main source of noise emission. Lower noise levels were recorded at the steering wheel with the 12 tooth gear pump than with the 9 tooth gear pump.
