剎(cha)車閥測試系統中制(zhi)動壓力的產(chan)生

氣(qi)(qi)壓(ya)(ya)剎(cha)車閥測(ce)(ce)試系(xi)統(tong)(tong)(tong)自檢正(zheng)常后(hou)，測(ce)(ce)試開始進(jin)(jin)行，首先根據(ju)欲(yu)剎(cha)車程(cheng)度，系(xi)統(tong)(tong)(tong)計(ji)算出(chu)伺服電(dian)機給定量，進(jin)(jin)而控(kong)制(zhi)制(zhi)動(dong)絲(si)桿驅動(dong)踏(ta)板下(xia)壓(ya)(ya)，通(tong)過(guo)(guo)力(li)及角度傳(chuan)感(gan)器測(ce)(ce)量施加于(yu)踏(ta)板上(shang)的(de)(de)力(li)及踏(ta)板下(xia)壓(ya)(ya)角度，踏(ta)板下(xia)壓(ya)(ya)后(hou)使進(jin)(jin)氣(qi)(qi)閥打(da)開產生(sheng)制(zhi)動(dong)壓(ya)(ya)力(li).　　通(tong)過(guo)(guo)制(zhi)動(dong)管路(lu)內的(de)(de)壓(ya)(ya)力(li)傳(chuan)感(gan)器測(ce)(ce)量出(chu)氣(qi)(qi)閥的(de)(de)壓(ya)(ya)力(li)值(zhi)(zhi)進(jin)(jin)而判斷試品是否(fou)合(he)格。試驗(yan)(yan)信(xin)息(xi)的(de)(de)輸出(chu)和數(shu)(shu)據(ju)采集的(de)(de)整個過(guo)(guo)程(cheng)時間非(fei)常短(duan)，因此設(she)計(ji)系(xi)統(tong)(tong)(tong)由計(ji)算機系(xi)統(tong)(tong)(tong)完全自動(dong)控(kong)制(zhi)。　　在(zai)(zai)試驗(yan)(yan)過(guo)(guo)程(cheng)中(zhong)，以上(shang)6點是柱塞泵(beng)可維修的(de)(de)方面通(tong)過(guo)(guo)報警(jing)信(xin)號指示(shi)(shi)燈和面板數(shu)(shu)值(zhi)(zhi)顯示(shi)(shi)及形用(yong)(yong)來據(ju)橡(xiang)樹嶺(ling)國家實驗(yan)(yan)室消息(xi)觀察當前(qian)系(xi)統(tong)(tong)(tong)的(de)(de)運行狀況(kuang)。試驗(yan)(yan)結(jie)束(shu)后(hou)，邏輯單(dan)元通(tong)過(guo)(guo)對試驗(yan)(yan)數(shu)(shu)據(ju)的(de)(de)分析(xi)，得出(chu)相(xiang)應的(de)(de)測(ce)(ce)試結(jie)果(guo)，并通(tong)過(guo)(guo)報警(jing)信(xin)號指示(shi)(shi)燈直(zhi)觀地(di)顯示(shi)(shi)出(chu)測(ce)(ce)試結(jie)果(guo)。試驗(yan)(yan)結(jie)束(shu)后(hou)，進(jin)(jin)行數(shu)(shu)據(ju)處理分析(xi)和輸出(chu)相(xiang)應測(ce)(ce)試結(jie)果(guo)。　 剎(cha)車閥測(ce)(ce)試設(she)備(bei)采用(yong)(yong)模(mo)塊化結(jie)構：由氣(qi)(qi)源、試驗(yan)(yan)臺架、電(dian)氣(qi)(qi)系(xi)統(tong)(tong)(tong)3個獨立部(bu)分組成。氣(qi)(qi)源部(bu)分采用(yong)(yong)兩體(ti)結(jie)構：氣(qi)(qi)缸、過(guo)(guo)濾器為一體(ti)，Tepex材料結(jie)合(he)DLFT工藝(yi)固定在(zai)(zai)試驗(yan)(yan)系(xi)統(tong)(tong)(tong)上(shang)；兩通(tong)電(dian)磁閥、過(guo)(guo)濾減(jian)壓(ya)(ya)閥等為另一體(ti)，接口采用(yong)(yong)浮(fu)動(dong)接頭的(de)(de)形式以便(bian)于(yu)連接。
