砌墻磚磁力(li)(li)振動(dong)臺(tai)主要由(you)臺(tai)面(mian)，底(di)架及振動(dong)電(dian)(dian)機(ji)組(zu)成。結構如圖所示。臺(tai)面(mian)與(yu)(yu)底(di)架均(jun)系型鋼(gang)焊接結構，具有(you)一定(ding)(ding)的剛性(xing)。中間墊入硬(ying)性(xing)橡(xiang)膠，它是活(huo)動(dong)臺(tai)面(mian)與(yu)(yu)固定(ding)(ding)底(di)架之間的減振支(zhi)撐(cheng)裝置起(qi)消振作用。在(zai)底(di)架上部(bu)裝有(you)六只定(ding)(ding)位銷與(yu)(yu)臺(tai)面(mian)底(di)部(bu)六只定(ding)(ding)位孔相配，保(bao)證(zheng)活(huo)動(dong)臺(tai)面(mian)在(zai)振動(dong)時(shi)定(ding)(ding)位。固定(ding)(ding)在(zai)活(huo)動(dong)臺(tai)面(mian)底(di)部(bu)的振動(dong)電(dian)(dian)機(ji)是采(cai)用雙(shuang)向出(chu)軸電(dian)(dian)機(ji)，在(zai)軸兩端(duan)裝有(you)需要的激(ji)動(dong)力(li)(li)，使振動(dong)臺(tai)面(mian)產(chan)生(sheng)振

砌墻磚磁(ci)力(li)振(zhen)動(dong)(dong)(dong)臺(tai)是一種(zhong)在(zai)普(pu)(pu)通(tong)振(zhen)動(dong)(dong)(dong)臺(tai)基礎(chu)上的(de)更新(xin)改良產品。本(ben)產品外形規格為1000mm*1000mm重量是原普(pu)(pu)通(tong)振(zhen)動(dong)(dong)(dong)臺(tai)的(de)1.7倍，臺(tai)面(mian)下方附(fu)有磁(ci)盤，通(tong)電上磁(ci)，磁(ci)盤吸(xi)力(li)可達到75千(qian)克力(li)左右，斷(duan)電后磁(ci)力(li)自動(dong)(dong)(dong)消失。這樣(yang)既免去(qu)了(le)安(an)裝時必打(da)地(di)基的(de)程序，又解決了(le)實驗過程中須將(jiang)試(shi)件緊固在(zai)臺(tai)面(mian)上的(de)問題。并(bing)且開關設有定時裝置，使(shi)用起來更加簡單方便。
