Musculoskeletal injuries are well-k

Musculoskeletal injuries are well-known disorders among the agricultural tractor operators. Overexertion is a critical factor which can agitate these injuries. Physical body characteristics should be measured for an ergonomically best-fit-optimal design for the operators. In this study, a designed setup was employed to derive the applied forces by tractor operators on the control tools. The different muscle strengths including leg/foot strength, hand push/pull strength, and torque strength applied by both hands were measured. A comparison was made for the obtained values for different strengths by considering the effects of hand dominance. The obtained data were used to estimate the maximum allowed forces in these tools. In contrast to the previous studies, the minimum allowed actuating forces of the pedals were calculated using reasonable assumptions. These values could provide more comfort and less exhaustion for the tractor operators. The obtained ranges were benchmarked against corresponding recommended values in some standards (ISO, ISIRI, and ASABE family). The results revealed the unsuitability of evaluated standards for a proper design and the excessive overestimation of those recommended values (in some cases more than 3 times). In all of the design procedure, a suitable attention was paid to accommodate it with more than 90% of target population.

肌肉骨骼損傷是公知的病症的農用拖拉機運營商之間。虛勞是能夠攪動這些損傷的關鍵因素。身體特徵應該為對於操作者的人體工程學最佳擬合最佳設計來測定。在這項研究中，所設計的設置被用來導出所述控制工具通過拖拉機操作人員施加的力。在不同的肌肉強度，包括腿/足的強度，手推/拉強度和抗扭強度施加由雙手進行了測定。比較是為獲得值進行考慮慣用手的影響，不同的優勢。所得數據用於估計這些工具允許的最大力量。相較於以前的研究，最小允許致動所述踏板的力用合理的假設來計算。這些值可用於拖拉機運營商提供更多的舒適和更少的疲勞。將所得到的範圍分別為基準針對在某些標準（ISO，ISIRI，和ASABE家族）對應的推薦值。結果顯示的評價標準不適合用於適當的設計和那些推薦值的過度過高估計（在一些情況下超過3次）。在所有的設計程序的，合適的注意了具有超過90％，以適應它的目標人群。結果顯示的評價標準不適合用於適當的設計和那些推薦值的過度過高估計（在一些情況下超過3次）。在所有的設計程序的，合適的注意了具有超過90％，以適應它的目標人群。結果顯示的評價標準不適合用於適當的設計和那些推薦值的過度過高估計（在一些情況下超過3次）。在所有的設計程序的，合適的注意了具有超過90％，以適應它的目標人群。
