you can create a test project and add load tests to your project 可以創(chuàng)建測(cè)試項(xiàng)目并向項(xiàng)目中添加負(fù)載測(cè)試。
for separated push rod, switch on, under no-load condition, the oil cylinder makes reciprocating movement for several times, to discharge air in the cylinder and oil pipeline, then adds load 分體推桿,接上電源讓油缸在無(wú)負(fù)載情況下,往復(fù)動(dòng)作數(shù)次使油缸和油管中空氣排出、再帶上負(fù)載。
the experiment procedure and analysis result about exteriorly extended end-plate connection with high strength bolt are introduced primarily; each sample's dimension is given . the adding load equipment, measuring apparatus placed, measuring point established is detailed . adding load measure load and m-curve is produced; the single span gabled frames horizontal displacement formula is deduced when the horizontal concentrated force is applied to it 重點(diǎn)介紹了外伸端板高強(qiáng)螺栓連接的實(shí)驗(yàn)過程及實(shí)驗(yàn)分析結(jié)果,介紹了各組試件的形狀尺寸、加載裝置、測(cè)量?jī)x器安放、測(cè)點(diǎn)的布置等;給出加載方式及測(cè)出的m-曲線;計(jì)算出試驗(yàn)節(jié)點(diǎn)的初始剛度;推導(dǎo)水平集中力作用下單跨門式剛架考慮節(jié)點(diǎn)半剛性的側(cè)移計(jì)算公式。
