摘要: Small-scale farmers often use motorised backpack sprayers to apply chemicals crops. However, vibration from their internal combustion engines and other motive parts, such as pumps, is transmitted the operator's body this could cause harm. Vibration signals a sprayer were measured using 3-axis accelerometers attached frame of wrist, chest, head neck. The results fast Fourier transform analysis showed peak in horizontal vibrations 3 m s−2 at frequency 20 Hz. According ISO-2631-1 standard, outcome signifies that maximum continuous working time for practical under test should therefore not exceed 1 h.
