摘要：首先介绍了快锻液压机的国内外研究现状，指出了国内快锻液压机发展的不足。又分别分析了阀控液压传动系统、泵控液压传动系统和伺服液压传动系统的结构和原理，并以此为基础指出了3种液压传动系统的优缺点。相比于阀控液压传动系统和泵控液压传动系统，伺服液压传动系统具有伺服性能好、成本低、加工质量和精度高等优点。伺服液压系统非常适合应用于快锻液压机。最后总结了3种不同的液压传动系统的特点，指出伺服液压传动系统将成为快锻液压机传动系统的主要发展趋势。

Abstract: The research status of fast forging hydraulic press at home and abroad was introduced, and deficiencies of the fast forging press in the domestic development were pointed out. The structures and principles of valve controlled hydraulic transmission system, pump controlled hydraulic transmission system and servo hydraulic transmission system were analyzed, and the advantages and disadvantages of these three kinds of hydraulic transmission system were pointed out on the above basis. Compared with valve controlled hydraulic transmission system and pump controlled hydraulic transmission system, servo hydraulic transmission system has the advantages of good servo performance, low cost, high processing quality and precision. Servo hydraulic transmission system is very suitable for fast forging hydraulic press. Finally, the characteristics of three different hydraulic transmission systems were summarized, and servo hydraulic transmission system was regarded as the main trend of development in fast forging hydraulic drive system.
