中文摘要:对动力系统用两级先导式电磁阀进行了动力学分析。建立了基于电磁阀阀芯振动与流体流动相耦合的系统动力学模型。模型充分考虑了阀芯自激振动,阀内各腔以及阀前后管路内压力变化。分析了不同工作条件下阀芯的稳定性,研究了工作压力、工作流量对电磁阀动力学特性的影响。

Abstract:The dynamics of a pilot-operated two-stage solenoid valve used in power system were studied numerically. A dynamic model coupling vibration of solenoid valve with fluid flow in the valve was derived. While solving the system equations, vibration of the valve spindle, various pressure-flow characteristics across the valve ports and orifices and pressure variation in chambers were taken into consideration. The model was validated by experimental results. The simulation results present stability of the spindle for different operating conditions and effect of working pressure and working flow rate on dynamics of the solenoid valve.

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.
