摘要:

 对直驱式电液伺服系统在模锻锤上的应用进行了研究,提出一种新型直驱式电液伺服控制模锻锤。设计了模锻锤直驱式液压控制系统原理图,分析了其工作原理和优势,通过研究新型模锻锤能量控制原理,提出了蓄能间接转换控制方法及转换原理,通过理论分析证明可以提高系统能效及打击能量的可控性。分别对交流伺服电机调速系统与泵控缸系统进行了数学建模,在此基础上建立了模锻锤控制系统的数学模型,并在Simulink平台上搭建系统的仿真模型,仿真分析了该系统的动态特性,通过Bode图中的幅值裕量和相位裕量证明了系统的相对稳定性。时域仿真曲线表明,泵控系统动态响应时间可以满足模锻锤工况要求。仿真结果有效验证了直驱式电液伺服模锻锤控制系统的可行性。

 The application of direct drive electrohydraulic servo system on die forging hammer was studied, and a new direct drive electrohydraulic servo die forging hammer control system was proposed. Then, the direct drive hydraulic control system schematic of die forging hammer was designed, and the working principle and advantages were analyzed comprehensively. Through the study of energy control principle of the new die forging hammer, the indirect conversion control method of the energy storage and the conversion principle were proposed. The theoretical analysis proves that the energy efficiency of the system and the controllability of strike energy can be improved. Furthermore, the mathematical models of AC servo motor and pump control cylinder system were set up, and based on this, the mathematical model of direct drive electrohydraulic servo die forging hammer control system was established. On the Simulink platform, the simulation model of the system was built, and the dynamic characteristics of the system were simulated and analyzed. The relative stability of the system was proved by the amplitude margin and phase margin in the Bode diagram. It can be seen from the time domain simulation curve that the dynamic response time of the pump control system can satisfy the die forging hammer condition, and the feasibility of the direct drive electrohydraulic servo die forging hammer control system is verified effectively.
