摘要
由于混合装配系统(Mixed-Model Assembly Systems,MMAS)中种类繁多的装配零件/装配用工具没有合理的布局标准,且很少考虑工人的生理特性和认知习惯,提出基于人机工效的装配零件/装配用工具的布局优化方案。重点研究了单层布局、双层布局及各层装配零件/装配用工具的分离布局,以及对应装配零件/装配用工具的混合布局等影响因素。通过鼠标对装配零件/装配用工具进行点击抓取,移动至装配位置,记录过程操作时间。结果表明:双层布局中,较难观察的零件摆放在最佳视区时人的操作时间最短,装配效率最高;而单层布局中,处于最佳视区的装配零件/装配用工具对应混合布局的装配效率次之。最后,以某发动机的装配仿真实验验证了以上实验结论的合理性和有效性。
Due to many kinds of parts and tools, included in Mixed-Model Assembly Systems （MMAS）, have not a reasonable lay- out criterian, and almosfly consider workers＇ physiological property and cognitive habits, which affect the assembly efficiency of MMAS,raising the layout solutions of tools and parts based on the ergonomics. The common layout solutions are regarded as re- search contents. Those solutions include single layer and double layers. One kinds of them has disconnected layout and corre- sponding layout about tools and parts. Using mouse to choose the model of tools and parts, and move them to the fixing position. The research results show that in the double layout the people＇ s manipulation time is lowest when those models are positioned in the best visual area, and the assembly efficiency is higher. In addition, the way of tools and parts＇ s corresponding layout in the best visual area has the same assembly efficiency. Lastly, checking the rationality of results of the experimentation by MMAS sim- ulation experiment.
