摘要: 为解决柔性制造系统中资源重组引起的布局问题,采用面向对象的建模方法建立了柔性制造系统的虚拟仿真系统.该虚拟仿真系统通过对制造系统中各设备进行几何和行为建模,建立虚拟设备模型;采用生产计划流建立车间布局方案和调度模型.通过仿真,不仅能验证加工代码的正确性,还能根据加工工艺仿真结果分析布局的合理性和可行性,并对布局进行优化.最后,对2种布局进行了仿真,结果表明所建立的仿真系统是可行和有效的.Abstract: In order to solve the problem of facility layout induced by resource recombination in flexible manufacturing systems,an object-oriented modeling method was proposed to construct the virtual prototype system of a flexible manufacturing system.By modeling of the geometry and behavior of each facility in a manufacturing system,virtual facility models are formed,and by adopting the production schedule flow,a facility layout scheme and dispatch model are constructed.The accuracy of NC(numerical code) can be validated,the rationality and feasibility of a layout scheme can be analyzed,and the layout scheme may be optimized by the simulation of a virtual prototype system.Finally,two different layouts were simulated.The simulation results show the effectiveness of the proposed method.
