秤(cheng)(cheng)臺是動(dong)(dong)態(tai)(tai)電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡的(de)(de)主要組成部分。其(qi)(qi)結(jie)構(gou)(gou)的(de)(de)機械(xie)強度(du)(du)和(he)(he)剛度(du)(du)是否滿(man)足要求(qiu)，極限(xian)是否合理，對測量(liang)(liang)精度(du)(du)起(qi)著至(zhi)關重(zhong)要的(de)(de)作(zuo)用(yong)。雖然動(dong)(dong)態(tai)(tai)電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡秤(cheng)(cheng)臺比靜(jing)態(tai)(tai)電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡要短得多，但其(qi)(qi)機械(xie)強度(du)(du)和(he)(he)剛度(du)(du)的(de)(de)結(jie)構(gou)(gou)應(ying)該高于(yu)靜(jing)態(tai)(tai)電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡，確保(bao)負載變(bian)形較(jiao)小的(de)(de)車(che)輛，和(he)(he)快速的(de)(de)響應(ying)速度(du)(du)，能(neng)準確和(he)(he)及時(shi)的(de)(de)通(tong)過(guo)重(zhong)力(li)信號測力(li)傳感(gan)器(qi)，當大(da)負載變(bian)形小于(yu)0.5毫米，其(qi)(qi)結(jie)構(gou)(gou)為J1共享頻率(lv)高，并具有(you)良好的(de)(de)動(dong)(dong)態(tai)(tai)特性(xing)。電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡在(zai)檢定(ding)時(shi)由于(yu)配備的(de)(de)標準器(qi)及相關配套設備，沉重(zhong)、繁(fan)雜、龐大(da)，且不(bu)(bu)同(tong)生產廠家(jia)的(de)(de)技(ji)術人員(yuan)、計量(liang)(liang)部門的(de)(de)檢定(ding)、修(xiu)理人員(yuan)及使(shi)用(yong)維護人員(yuan)所(suo)處(chu)的(de)(de)情(qing)(qing)況(kuang)千差萬別，技(ji)術知識水平亦參(can)差不(bu)(bu)齊。固(gu)(gu)定(ding)式軸重(zhong)秤(cheng)(cheng)，原理跟固(gu)(gu)定(ding)式電(dian)(dian)(dian)(dian)子(zi)汽車(che)衡基本相同(tong)。但固(gu)(gu)定(ding)式軸重(zhong)秤(cheng)(cheng)每次稱(cheng)量(liang)(liang)的(de)(de)是汽車(che)各(ge)軸重(zhong)量(liang)(liang)，通(tong)過(guo)累加(jia)獲得整車(che)重(zhong)量(liang)(liang)。可以采用(yong)動(dong)(dong)態(tai)(tai)和(he)(he)靜(jing)態(tai)(tai)兩種稱(cheng)量(liang)(liang)方式。優(you)點：可以滿(man)足各(ge)類(lei)汽車(che)軸重(zhong)的(de)(de)需求(qiu)，結(jie)構(gou)(gou)輕(qing)小，便于(yu)運(yun)輸、安裝(zhuang)調試。缺點：動(dong)(dong)態(tai)(tai)受(shou)車(che)速、車(che)型、路面狀(zhuang)況(kuang)等情(qing)(qing)況(kuang)的(de)(de)影響，精度(du)(du)較(jiao)低；靜(jing)態(tai)(tai)稱(cheng)量(liang)(liang)過(guo)程繁(fan)瑣(suo)，時(shi)間太長。
