由于(yu)(yu)(yu)存儲在該數(shu)據(ju)(ju)庫(ku)(ku)中的(de)(de)信(xin)(xin)息(xi)基(ji)本上是該單(dan)元特有的(de)(de)信(xin)(xin)息(xi)，因此結構(gou)數(shu)據(ju)(ju)庫(ku)(ku)必須由每(mei)個(ge)用(yong)(yong)(yong)戶單(dan)元自身(shen)創建。300t液(ye)壓(ya)(ya)機(ji)為(wei)了滿足執行機(ji)構(gou)運動(dong)速度的(de)(de)要(yao)求， 選用(yong)(yong)(yong)一個(ge)油(you)(you)(you)泵或(huo)多(duo)個(ge)油(you)(you)(you)泵。低壓(ya)(ya)（油(you)(you)(you)壓(ya)(ya)小(xiao)于(yu)(yu)(yu)2.5MP）用(yong)(yong)(yong)齒輪泵；中壓(ya)(ya)（油(you)(you)(you)壓(ya)(ya)小(xiao)于(yu)(yu)(yu)6.3MP）用(yong)(yong)(yong)葉片泵；高壓(ya)(ya)（油(you)(you)(you)壓(ya)(ya)小(xiao)于(yu)(yu)(yu)32.0MP)用(yong)(yong)(yong)柱塞泵。熱壓(ya)(ya)成型(xing)機(ji)驅(qu)動(dong)系統(tong)主要(yao)有泵直接驅(qu)動(dong)和泵-蓄(xu)能(neng)器驅(qu)動(dong)兩種(zhong)(zhong)型(xing)式。泵直接驅(qu)動(dong) 　這種(zhong)(zhong)驅(qu)動(dong)系統(tong)的(de)(de)泵向(xiang)液(ye)壓(ya)(ya)缸提供高壓(ya)(ya)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)液(ye)體(ti)，配流(liu)閥用(yong)(yong)(yong)來改變供液(ye)方(fang)向(xiang)，溢流(liu)閥用(yong)(yong)(yong)來調節系統(tong)的(de)(de)限(xian)定壓(ya)(ya)強(qiang)，同時(shi)起(qi)安(an)全溢流(liu)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)(yong)。1200噸液(ye)壓(ya)(ya)機(ji)一種(zhong)(zhong)以(yi)液(ye)體(ti)為(wei)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)介(jie)質(zhi)，用(yong)(yong)(yong)來傳(chuan)遞能(neng)量(liang)以(yi)實現各種(zhong)(zhong)工(gong)(gong)藝的(de)(de)機(ji)器。液(ye)壓(ya)(ya)機(ji)除用(yong)(yong)(yong)于(yu)(yu)(yu)鍛(duan)壓(ya)(ya)成形(xing)外，也(ye)可用(yong)(yong)(yong)于(yu)(yu)(yu)矯(jiao)正、壓(ya)(ya)裝、打包、壓(ya)(ya)塊和壓(ya)(ya)板(ban)等。液(ye)壓(ya)(ya)機(ji)包括水壓(ya)(ya)機(ji)和油(you)(you)(you)壓(ya)(ya)機(ji)。以(yi)水基(ji)液(ye)體(ti)為(wei)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)介(jie)質(zhi)的(de)(de)稱為(wei)水壓(ya)(ya)機(ji),以(yi)油(you)(you)(you)為(wei)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)介(jie)質(zhi)的(de)(de)稱為(wei)油(you)(you)(you)壓(ya)(ya)機(ji)。四柱萬能(neng)液(ye)壓(ya)(ya)機(ji)它的(de)(de)原理是利(li)用(yong)(yong)(yong)帕斯(si)卡定律制成的(de)(de)利(li)用(yong)(yong)(yong)液(ye)體(ti)壓(ya)(ya)強(qiang)傳(chuan)動(dong)的(de)(de)機(ji)械，種(zhong)(zhong)類(lei)很多(duo)。當然，用(yong)(yong)(yong)途(tu)也(ye)根據(ju)(ju)需要(yao)是多(duo)種(zhong)(zhong)多(duo)樣的(de)(de)。如(ru)按傳(chuan)遞壓(ya)(ya)強(qiang)的(de)(de)液(ye)體(ti)種(zhong)(zhong)類(lei)來分，有油(you)(you)(you)壓(ya)(ya)機(ji)和水壓(ya)(ya)機(ji)兩大類(lei)。 它有時(shi)可能(neng)非常大，有時(shi)會存儲一些關于(yu)(yu)(yu)高級產品的(de)(de)最新信(xin)(xin)息(xi)。 在這種(zhong)(zhong)情況下(xia)，需要(yao)專門的(de)(de)數(shu)據(ju)(ju)庫(ku)(ku)管理程(cheng)(cheng)序DAKON，其功能(neng)和流(liu)程(cheng)(cheng)圖(tu)如(ru)圖(tu)5.5所示，液(ye)壓(ya)(ya)系統(tong)靜態特性仿真(zhen)程(cheng)(cheng)序

液(ye)(ye)壓機(ji)液(ye)(ye)壓系(xi)(xi)統(tong)(tong)(tong)仿真程(cheng)(cheng)(cheng)序(xu)系(xi)(xi)統(tong)(tong)(tong)的(de)模塊結(jie)構，以及各個程(cheng)(cheng)(cheng)序(xu)模塊在一(yi)定層(ceng)次(ci)上的(de)并行性，使(shi)得(de)可以增加一(yi)些模塊對系(xi)(xi)統(tong)(tong)(tong)進行擴(kuo)展(zhan)。系(xi)(xi)統(tong)(tong)(tong)擴(kuo)展(zhan)的(de)一(yi)個實例是建立一(yi)個靜(jing)態程(cheng)(cheng)(cheng)序(xu)來(lai)模擬(ni)液(ye)(ye)壓系(xi)(xi)統(tong)(tong)(tong)的(de)靜(jing)態特性。這樣(yang)的(de)程(cheng)(cheng)(cheng)序(xu)通過(guo)迭(die)代過(guo)程(cheng)(cheng)(cheng)來(lai)求解(jie)系(xi)(xi)統(tong)(tong)(tong)。該程(cheng)(cheng)(cheng)序(xu)需要一(yi)個以系(xi)(xi)統(tong)(tong)(tong)參數(shu)(shu)(shu)和方程(cheng)(cheng)(cheng)作(zuo)為(wei)輸(shu)入(ru)信息的(de)數(shu)(shu)(shu)據文件，其形(xing)式與輸(shu)入(ru)到 simha 程(cheng)(cheng)(cheng)序(xu)的(de)數(shu)(shu)(shu)據文件相(xiang)同。圖5.8顯示了資料流程(cheng)(cheng)(cheng)圖和程(cheng)(cheng)(cheng)序(xu)在整(zheng)個程(cheng)(cheng)(cheng)序(xu)系(xi)(xi)統(tong)(tong)(tong)中的(de)位置(zhi)。

程序要么(me)通(tong)過人機對話(hua)輸入數學模(mo)(mo)型(xing)，要么(me)講斯特(te)魯布和(he)AKDA建(jian)立的數學模(mo)(mo)型(xing)，將輸出結果存儲(chu)在外部(bu)存儲(chu)區，讓(rang)程序GRASA以特(te)性曲線(xian)的形式輸出結果。此(ci)外，計算(suan)結果可以在打印(yin)機上打印(yin)出來。

STATB通過人機對話內容進(jin)行管理(li)控(kong)制(zhi)，不但可(ke)以能夠(gou)提高計算某個企(qi)業工作 點上的靜(jing)態特(te)性(xing)，而(er)且我們還能計算整條曲(qu)線(xian)，特(te)別具(ju)有(you)重要的是(shi)可(ke)用來發展(zhan)進(jin)行液壓(ya)技術系統的計算機試(shi)驗，這一點將在" 6.4"節(jie)中進(jin)一步說明。

程(cheng)序使用(yong)與Simha模擬程(cheng)序相(xiang)同的子(zi)程(cheng)序來計算(suan)方程(cheng)組中的系數和變量（除了它們變化很(hen)小）。 這表明(ming)標準算(suan)法也可以用(yong)于靜態特性仿真。
