摘要
汽车驱动桥调试是汽车总装配线上的一个重要作业,作业姿势不当会导致操作工人颈部和肩部疾病。利用DELMIA仿真软件对现场工作姿势进行人机工程学分析,并用快速上肢评估(RULA)来确定其风险等级,提出了改进操作的方案,并用仿真软件验证了其效果。结果表明:通过增加工作台阶,可以改善上臂和颈部的姿势,减少了工作紧张的风险;应用DELMIA可以对工作姿势进行量化评估,使分析过程更加直观和科学。
The automobile drive-axle commissioning station, an important station along the assembly line, is a location at which workers exhibit symptoms of neck and shoulder discomfort. Using the DELMIA simulation software, we evaluate the rapid upper-limb assessment （RULA） score of the current working posture to determine its risk. To overcome this risk, a scheme that improves operation is proposed and simulation software is used to verify its effect. The results indicate that the upper ann and neck posture is improved and the risk of job strain is reduced by increasing the lifting step. The application abstract process of postural assessment, which makes of DELMIA allows for the quantification ofvthe complex and the process more intuitive and data analysis more scientific.
