Structure design and performance characteristics of synchron system and hydraulic accumulator of hydraulic sheet shears used in uncoiling line have been introduced 摘要介紹了用于開(kāi)卷線的液壓剪板機(jī)的同步系統(tǒng)和液壓蓄能器的結(jié)構(gòu)設(shè)計(jì)及其性能特點(diǎn)。
Although self - syn chronous vibration and vibratory synchro nization transmission have been applied , in , mechanical engineering successfully , the , transient processes of self - synchron ization and synchronization transmission , in vibratory machines are still obscure . the physical processes of vibratory mac hines from asynchronous condition to syn chronous condition or from one type of s ynchronous condition to another co uld not be explained quantitatively acco rding to available , mechanical models . in this paper the pro blem is addrested specially 自同步振動(dòng)和振動(dòng)同步傳動(dòng)在機(jī)械工程上已獲得成功應(yīng)用,但是振動(dòng)機(jī)械實(shí)現(xiàn)自同步振動(dòng)和振動(dòng)同步傳動(dòng)的過(guò)渡過(guò)程長(zhǎng)期以來(lái)卻一直不明確,利用現(xiàn)有的振動(dòng)機(jī)械模型還不能定量解釋系統(tǒng)從不同步到同步、或是從一種同步狀態(tài)過(guò)渡到另一種同步狀態(tài)的物理過(guò)程。
