Frictional torque and mountain torque are of the same order and show similar seasonal variation , but the latter shows more complex spacial distribution 對(duì)摩擦和山脈力矩分析計(jì)算表明山脈和摩擦力矩同量級(jí),季節(jié)變化相似,但摩擦力矩的空間分布較山脈力矩簡(jiǎn)單。
The paper makes a systematic study on frictional torque model for hydraulic system , after the analysis of the ultra ? low speed principle of closed - loop system , it can be concluded that the existence of the difference between static frictional and dynamic frictional torque , and the periodic saltation of the dynamic frictional torque , are the main reasons of the low speed stick - skip to the electrohydraulic position servo system 針對(duì)伺服馬達(dá)的低速性能,進(jìn)行了低速實(shí)驗(yàn)研究,并兼顧快速性能進(jìn)行了階躍響應(yīng)和正弦響應(yīng)實(shí)驗(yàn)研究,對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行了分析,得出了一些有價(jià)值的結(jié)論,提出下一階段進(jìn)行實(shí)驗(yàn)的建議。
