style="text-indent:25px">液壓伺服系統(tǒng)具有響應(yīng)速度快、輸出功率大、控制精確性高等突出優(yōu)點(diǎn)，因而在航空航天、冶金、交通、工程機(jī)械等領(lǐng)域得到普遍應(yīng)用。電液位置伺服控制系統(tǒng)以液體作為動力傳輸和控制介質(zhì)，利用電信號進(jìn)行控制輸入和反饋。只要輸入某一規(guī)律的輸入信號，執(zhí)行元件就能啟動、快速并準(zhǔn)確地復(fù)現(xiàn)輸入量的變化規(guī)律。伺服系統(tǒng)性能的基本要求有哪些？精度高。伺服系統(tǒng)的精度是指輸出量能復(fù)現(xiàn)出輸入量的精確程度。穩(wěn)定性好。穩(wěn)定是指系統(tǒng)在給定輸入或外界干擾的作用下，能在短暫的調(diào)節(jié)過程后，達(dá)到新的或者恢復(fù)到原來的平衡狀態(tài)。伺服液壓系統(tǒng)射流管一般做成收縮形或拉瓦爾管形，當(dāng)流體流經(jīng)射流管時(shí)，將壓力轉(zhuǎn)換成動能射入接收器。滾動疲勞試驗(yàn)機(jī)定制</p><p
