概括

这项研究比较了观察性人体工程学方法,Ovako工作姿势分析系统 (OWAS) 和快速全身评估 (REBA),与举重期间的生物力学数据. 研究结果表明,这些方法可以表明负载差异,但并不总是产生相同的生物力学值.

科学领域:

人体工程学和生物力学
职业健康和安全问题职业健康和安全问题

背景情况:

对生物力学数据进行观察性人体工程学方法的有效性评估对于准确的风险评估至关重要.
与OWAS和REBA等观察工具与体内测量相比较的同时有效性研究很少.

研究的目的:

将Ovako工作姿势分析系统 (OWAS) 和快速全身评估 (REBA) 的观察方法与体内生物力学负荷测量进行比较.
评估OWAS和REBA在评估手动提升姿势时的标准有效性.

主要方法:

14名参与者进行了腰和腰.
在部,脊柱和膝盖进行了体内负荷测量.
来自OWAS和REBA行动水平 (AL) 的数据与生物力学负载数据进行了比较.

主要成果:

无论是OWAS还是REBA的动作水平 (AL),都成功地区分了手动提升任务期间在体内负载测量的变化.
同样的OWAS和REBA作用水平并不总是与同等的体内平均负荷测量结果相对应.
与俯卧式起重技术相比,俯卧式起重技术显示了与工作相关的肌肉骨疾病的风险更高.

结论:

像OWAS和REBA这样的观察方法对于在手动提升中区分负载水平是有用的.
在直接比较来自OWAS和REBA相同行动水平的生物力学负载值时,建议谨慎.
式举重比式举重对肌肉骨疾病的风险更大.

关键词:

Design Consideration

Design Consideration

Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

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.
