Abstract

Electro-hydraulic excitation systems are key equipment in various industries. Electric motor driving rotary valves are mostly used in existing systems. However, due to the separate design of the driving and hydraulic parts, highly compact integration cannot be achieved by these type of systems. Moreover, investigation on the influence of relevant parameters on the system has been insufficient in previous studies. To overcome these problems, a novel full electro-hydraulic excitation system scheme as well as a parameters analysis are presented in this paper. Theoretical models of the flow areas for valve orifices of different geometric shapes are obtained, based on which an AMESim ® simulation model of the system is established. The effects of the main parameters are analyzed using numerical simulations, and the coupling relationship of the parameters is revealed. The results demonstrate the feasibility and effectiveness of the proposed method. Experimental studies were conducted to verify the effectiveness of the proposed system scheme and the analysis results. We found that a highly compact integration can be obtained while maintaining a high reversing frequency. We also found that the proposed system has a certain level of load adaptability, which is superior to the existing methods.
