【摘要】 同步驱动系统是机电液一体化技术的一个重要领域，在工业生产中得到广泛应用。与其它同步驱动方式相比，液压同步驱动具有结构简单、组成方便、易于控制和适宜大功率场合等诸多优点。而同步驱动系统的关键是高效高同步精度问题。因此，如何来开发、研制出高效高精度的同步驱动系统就成为工程技术人员普遍关心和攻克的难题。 本课题针对传统的两种同步控制方式：阀控同步方式与泵控同步方式存在的缺点，提出综合采用容积泵控与阀控的复合控制方式来加以改进，充分利用泵控与阀控的各自优点，最大限度地改进了同步系统的同步运行性能。阀泵复合控制的系统在动态调节过程中主要利用阀控输出保证动态性能，在稳态调节时主要利用双联泵控进行调节。本论文的主要内容如下： 1．探讨了采用机液伺服阀控作为补偿的同步复合控制系统，并对其数学模型进行了较详细的分析研究。 2．进一步提出了利用电液比例阀控作为辅助补偿系统的复合同步控制系统，进行了计算分析。 3．利用模拟实际工况的试验系统和同步误差在线检测系统、利用Wisdows环境下的VB开发出数据自动采集软件，对上述同步系统进行不同条件下的同步性能评估。更多还原

【Abstract】 The synchronization driver system is one important area of integrative technology among mechanism electronics and hydraulic. It was widely applied in industry. Comparing with other synchronization modes, the synchronization mode with hydraulic have many advantages, such as simple structure, composed-easily, controlled-easily, suited for high power condition, etc. The key to synchronization system is high efficiency and synchro-precision problem. As a result, how to design and develop a high efficiency and precision synchro-system is a difficult problem that is cared by many engineering technicians. This paper aims to the defects of two traditional synchro-control modes: valve-control and pump-control, and brings forward a complex control system with pump-control and valve-control together to improve. This complex system makes the best of the advantages of pump-control and valve-control each other, and improve the synchro-running capability of the system as possible. This complex control system mainly utilizes the valve- control抯 output to ensure dynamic capability during dynamic adjustment. and uses pump-control to carry out adjustment in the process of static state. The main content of the paper is listed as follow: 1. Discuss a synchronization and complex control system with hydro- mechanical servo?valve-control as the compensation system, and analysis and study the system抯 mathematics model detailed. 2. Bring forward another complex control system with electro- hydraulic proportional valve-control as the compensation system, and also analysis the system. 3. Evaluate the synchro-capability of each synchro-system with simulating test system~ synchro-error detecting system and data automatic II collection software, which was developed with Visual Basic language in windows OS flat roof.更多还原
