Honing Machine Spindle Reciprocating Motion Electro-hydraulic Proportional Control System Design And Research

Honing machine is a kind of important equipment in metalworking industry. In recent years, many kinds of new technologies are used in honing machine, such as, control technology, double bulge honing caput technology, morden measurement, etc. Foreign honing machine technology has achieved rapid development, which challenges inner companies. In our country, traditional technologe and honing machine manufacture restrict honing technology widely application. Our country companies' product for honing machine, most of them are in the semi-automation level, and cannot meet advanced market needs, which affect our country's equipment manufacture development.The thesis researches reciprocating motion of honing machine spindle, which is one of important parts for honing machine technology upgrade. We will replace original switch control by electrohydraulic proportional control. In static design, we choose important system elements and determine system control scheme, which provide good basis for the open-loop control and closed-loop control. According to the system's property, we set up the system's mathematical model. In closed-loop control, we has achieved good dynamic output by control strategy research, which meet design needs.In the research of this thesis, we use application and practicability as criteria for design plan and research content. For control plan choice, firstly, we choose open-loop control. In this foundation, we research closed-loop control. In the control strategy, we choose several simple practical control policies, such as, PID control, fuzzy control, fuzzy self-adaptive control, which provide good basic condition for controller design and software programming.
