中文摘要:为了克服传统电液变频系统响应速度慢的缺点,设计了一种基于能量调节的电液变频调速系统,系统中带有能量调节装置,该装置能够在系统减速时吸收多余的能量,而在系统加速时释放储存的能量,从而加快系统响应速度。进行了3种液压调速方式的对比实验,实验表明,本系统能够在加速和减速时都拥有很好的动态特性,接近节流调速系统;并且具有良好的功率匹配特性,节流及溢流损失很小,甚至低于传统的电液变频调速系统。

Abstract:A variable frequency electro-hydraulic control system based on energy regulation was developed to improve slow respondence of the conventional variable frequency electro-hydraulic systems. An energy regulation device which could store redundant energy while hydraulic system was in decelerating period as well as release energy while the system was in accelerating period was employed in the variable frequency electro-hydraulic control system. This will enhance the dynamic characteristics of the variable frequency electro hydraulic control system. The experiments results which were compared with two other control systems showed that the variable frequency electro-hydraulic control system had excellent dynamic characteristics which like valve control systems. Furthermore, the throttle and relief energy loss of this system was little and even lower than conventional variable frequency hydraulic control systems.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
