Power tiller: vibration magnitudes and intervention development for vibration reduction.

摘要: Abstract The operators of power tiller are exposed to a high level vibration originating from the dynamic interaction between soil and machine. is transmitted handle hands, arms shoulders. In present study, experiments were conducted in three operational conditions i.e. transportation on farm roads, tilling with cultivator rota-tilling rota-vator. highest values observed x-direction all experiments. maximum rms values for 5.96, 6.81 and 8.00 ms −2 cultivator, respectively. Three materials used intervention development reduce magnitude. reduction 25.30, 31.21 30.45% transportation; 23.50, 30.64 20.86% 24.03, 29.18 25.52% achieved polyurethane (PU), rubber combination PU intervention. It was found that reductions conditions. average exposure time occurrence white finger syndrome increased by 28–50% incorporation different operations. Physiological postural parameters also improved interventions.
