上海朝輝(hui)微壓力(li)傳感器在測量過程,即(ji)壓力(li)直接作用在傳感器的(de)膜片(pian)上,使(shi)膜片(pian)產生與介質壓力(li)成正(zheng)比(bi)的(de)微位移,使(shi)傳感器的(de)電(dian)阻發(fa)生變(bian)化,同時通過電(dian)子(zi)線路檢(jian)測這一變(bian)化,并轉(zhuan)換輸出一個對應于這個壓力(li)的(de)標(biao)準信號得過程。
對(dui)于微壓(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)來(lai)說,靈(ling)敏度和線(xian)性度是微壓(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)zui重(zhong)要的(de)(de)兩個性能指標。為了制作出能夠(gou)滿足實際應用需求(qiu)的(de)(de)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi),必需探索出一(yi)種微壓(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)靈(ling)敏度和線(xian)性度的(de)(de)有(you)(you)效(xiao)仿真(zhen)方法。實際的(de)(de)研(yan)究(jiu)中,發現一(yi)種基于對(dui)壓(ya)(ya)(ya)阻式壓(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)薄膜表面應力(li)(li)的(de)(de)有(you)(you)限元分析(FEA)和路徑(jing)積分的(de)(de)仿真(zhen)方法。通過(guo)這一(yi)方法實現了在(zai)(zai)滿量程范圍內不同壓(ya)(ya)(ya)力(li)(li)值下對(dui)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)電壓(ya)(ya)(ya)輸出值的(de)(de)估計,在(zai)(zai)此基礎(chu)上(shang)對(dui)壓(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)的(de)(de)靈(ling)敏度和線(xian)性度進行了有(you)(you)效(xiao)仿真(zhen)。
