摘要
合流节点作为装配线重要组成部分,具有输送负载单元作用。从单个、两个合流节点输送能力最大化以及无堵塞为出发点,对三种控制策略进行了理论分析,分别得出最小发送时间间隔应满足的条件,并推导出有多个合流节点时应满足的最小时间间隔。用DEMIA/QUEST软件进行建模,采用SCL语言编写控制程序并进行仿真验证,对三种控制策略的仿真结果进行分析比较,得出理论分析的正确性。最后以案例说明只注重加工工位仿真,而忽略了合流等节点仿真带来的不利影响,并进行了优化,为工程师在最初设计时提供指导依据,同时也可以为制定MES系统提供参考。
The As an important part in assembly ＆ test line, the interflow node can transmit load-units. In order to avoid jams and maximize transport ability of one or two rotating stations, three pass and con- trol strategies are analyzed theoretically, then conditions that can result in a minimum sending interval are concluded separately, and the least interval with respect to several rotating stations is determined. The validity of theoretical analysis is proved by employing DEMIA/QUEST software to model and using SCL language to compile control program for simulation and by comparing the results of three simulations. At last an example is used to illustrate the influence of ignoring simulation of interflow node; also it is opti- mized, which can be used as a reference for engineers to design logistics system and MES system.
