摘要
为了减小电液伺服斜盘柱塞式液压变压器的压力冲击,降低噪声,提高其运行平稳性,本文基于ADINA软件的流固耦合功能对液压变压器的配流盘缓冲槽进行了研究.在Pro/E中建立了配流结构的流体模型和固体模型,导入到ADINA软件中建立有限元模型,分析了配流缓冲结构的流场,并对结构进行了有限元校核,设计制造了带有三角槽缓冲结构的配流盘,基于搭建的液压变压器实验台进行了实验研究.结果表明所设计的配流盘能够使液压变压器运行平稳,最低转速达到35 r/min,噪声显著降低,可靠性明显提高,验证了理论分析的正确性.
To reduce the pressure shock of the electro-hydraulic-servo piston hydraulic transformer with swash plate, to lower the noise and to improve the operational stability, this paper develops buffer slot in the valve plate of the hydraulic transformer based-on the fluid-structure coupling function of the software ADINA. In software Pro/E, fluid model and solid model of the flow assignment structure of valve plate are built and imported to the software ADINA for building of finite element model. The flow field of the flow assignment structure that was checked with finite element method was analyzed. A valve plate with buffer slot with triangle shape was manufactured and tested on hydraulic transformer test-bed. The results revealed that the valve plate enabled hydraulic transformer steady in operation and the minimum speed of hydraulic transformer reached 35 r/min. The noise was lower and the reliability was improved. The correctness of theoretical analysis was testified.
