概括

调整Dungeness分类桌的高度可以通过减少干曲来减少腰部受伤. 然而,这种变化可能会增加肩部的紧张,突出显示出需要平衡的人体工程学解决方案.

科学领域:

职业健康职业健康职业健康职业健康
人体工程学就是人体工程学.
生物力学生物力学

背景情况:

西海岸Dungeness捕捞的肌肉骨损伤率很高,特别是腰部疼痛.
尬的排序桌高度是被怀疑导致过度的箱体曲和背部负荷的原因.

研究的目的:

为了研究不同分类桌高度对腰部和肩膀生物力学负荷的影响.

主要方法:

25名参与者在三个不同的桌子高度分类.
测量包括干和肩膀关节的角度,时刻,肌肉活动,感知到的劳动力和不适.

主要成果:

增加的桌子高度减少了车身的曲和腰部神经关节 (L5/S1) 关节的时刻.
相反,较高的桌子导致肩膀曲时刻和上梯形肌活动增加.
感知到的劳累和不适没有受到桌子高度的显著影响.

结论:

提高排序桌可以减轻腰部的压力,但可能会增加肩部的压力.
人体工程学的桌子设计应该平衡背部和肩膀的生物力学负荷.

Machines: Problem Solving II

Machines: Problem Solving II

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Applications of Stress

Applications of Stress

Consider a structure made of a boom and a rod designed to support a load. These two components are connected by a pin and stabilized by brackets and pins. The boom and the rod are detached from their supports to assess the different stresses imposed on this structure, and a free-body diagram is drawn. Then, all the forces applied, including the load acting on the structure, are identified. The reaction forces exerted on both the boom and the rod are computed using the equilibrium equations.
