摘　　要：为改善电静液作动系统的能效和动态性能,提出了一种双变量电静液作动系统构型。该构型利用双变量液压泵和蓄能器,通过调整电机速度和液压泵的排量来控制作动器的输出位移。分析了所设计的电静液作动系统的工作原理,建立了相乘耦合非线性模型,并利用液压仿真工具AMESim对其进行了定量分析。研究结果表明,与传统电静液作动系统相比,所提出的双变量电静液作动系统构型在动态响应和能效方面具有明显优势。To improve the energy efficiency and dynamic performance of electro-hydraulic actuation systems,this paper proposes a dual-variable electro-hydraulic actuation system configuration.This configuration utilizes a dual-variable hydraulic pump and an accumulator,with the actuator's output displacement determined by,adjusting the motor speed and the hydraulic pump's displacement.,Based on an analysis of the working principles of the designed electro-hydraulic actuator,a multiplicative coupling nonlinear model was established,and a quantitative analysis was conducted using the hydraulic simulation tool AMESim.The research results indicate that compared to traditional electro-hydraulic actuation systems,the proposed dual-variable electro-hydraulic actuation system configuration has significant advantages in terms of energy efficiency and dynamic response.
