摘　　要：针对高效率、可调速、高精度的同步驱动需求,将负载敏感控制用于双缸同步驱动。设计负载敏感同步驱动系统,阐明其工作原理,并基于AMESim平台建立该系统的仿真模型,在偏载和变速的工况下,研究该系统的同步特性,揭示影响系统同步精度的主要因素及规律。研究表明,所设计的负载敏感同步驱动系统具有抗偏载能力强、效率高、可调速的优点,系统分流误差随流量的增加而线性增加,随偏载的增加而非线性增加,增加幅度先大后小。In response to synchronous drive requirements of high efficiency,adjustable speed and high precision,load sensitive control is used for dual-cylinder synchronous drive.Load sensitive synchronous drive system is designed,its working principle is explained,and simulation model of the system is established based on AMESim platform.Under the condition of eccentric load and variable speed,synchronous characteristics of the system are studied and main factors affecting synchronization accuracy of system and laws are revealed.The research shows that the designed load sensitive synchronous drive system has the advantages of strong anti-eccentric load capability,high efficiency and adjustable speed.Shunt error of system increases linearly with increase of flow,and increases nonlinearly with increase of eccentric load.The increase range is large at first and then small.
