Effect of steering wheel vibration on drivers hands in a two-wheel drivers hand tractor

الملخص EN

The paper presents research results of the vibration transmitted from the steering wheel of the tractor with a 2-wheel drive to the driver’s hands.

The vibration measurements were carried out on the tractor randomly chosen from the collage of agriculture / university of Baghdad.

Before testing the tractor was examined and adjusted following the producer’s recommendations.

The vibration levels were measured during the operation tillage at idling and at full load .The field was 31.7 m above level sea.

Soil was treated at soil constant moisture (17-20 %) with depth of plowing (17 cm).

During operation the weather temperature was measured (15 C) and humidity was ( 27 % ) The vibration level on the steering wheel was measured and analyzed .The frequency-weighted acceleration(RMS) , given in , was calculated.

The vibration total value was defined as the root-mean-square of the three component value
