連續(xù)系統(tǒng)仿真

第12章連續(xù)系統(tǒng)仿真——液體灌裝線仿真設(shè)計一、實驗?zāi)康模?、了解液體灌裝系統(tǒng)設(shè)計。2、了解Tank、Fluid、Processor及Pipe元素的用法。3、學會分析連續(xù)生產(chǎn)工藝設(shè)備利用率。二、實驗原理及內(nèi)容液體灌裝系統(tǒng)是用于化工、醫(yī)藥、食品充填設(shè)備。液體灌裝線是一個自動定量連續(xù)生產(chǎn)的工程，其功能就是將大量的散裝液體物料自動分成預(yù)定重量的小份載荷形式的定量容器包裝。下面介紹某飲料生產(chǎn)線按訂單進行灌裝生產(chǎn)過程的仿真。平均每小時下達一批100聽的工作單，接到工作單后調(diào)度系統(tǒng)往車間發(fā)送100聽空易拉罐，沖洗組以每批10聽2min的速度沖洗到達的空易扯罐，檢驗組以2聽/min的速度對沖洗后的空易拉罐進行檢驗，罐裝組以10聽/min（235ml/聽）的速度往空易拉罐中罐裝飲料，封箱組用3min時間將24聽飲料封裝為一箱。罐裝前的飲料要在一個100L的殺菌器中經(jīng)過45min殺菌處理，然后經(jīng)過管道輸送到200L的儲藏容器中等待罐裝，提取組根據(jù)該容器的飲料容量提取散裝飲料，當儲藏容器中的飲料小于70L時，提取組以一批/min（約10L/批）的速度提取散裝飲料，當殺菌器中的飲料多于80L的時候不再提取，殺菌器開始進行殺菌。三、實驗步驟1、元素定義（Define）元素定義表兀素名稱類型數(shù)量說明DrumPart1散裝飲料TinPart1易拉罐BufBuffer2臨時庫存EmptydrumMachine1散裝飲料提取FilltinMachine5罐裝WashMachine1鋼材沖洗組服務(wù)中心InspectionMachine1檢驗組PackMachine1裝箱/封箱組ToinspectionConveyor1沖洗組到檢驗組的輸送系統(tǒng)TopackConveyor1從罐裝組到裝箱/封箱組的輸送系統(tǒng)ToshipConveyor1從裝箱/封箱組到庫存的輸送系統(tǒng)BeansFluid1液體計量CookerTank1殺菌后飲料儲藏容器ProcessProcessor1殺菌器PipePipe2飲料輸送系統(tǒng)2、元素可視化(Display)的設(shè)置3、各個元素細節(jié)(Dedail)設(shè)計四、實驗結(jié)果模型仿真中取系統(tǒng)默認的1的時間單位為lmin，運行60X24=1440仿真時間單位，如圖所示。
