摘要
设计了一种磁致伸缩轴向双柱塞泵驱动的作动器,并提出了一种新型的主动配流阀,以双磁致伸缩泵为核心动力元件,组成电静液作动系统,实现了作动器的双向连续位移输出。通过建立作动器系统各部分的数学模型,从原理上分析作动器的输出特性。搭建实验平台测试并验证了作动器在相同转速不同相位角下的流量输出特性。通过数学模型与实验的对比,预测了在不同管路长度下作动器的输出特性变化规律。实验结果表明,在驱动频率180 Hz下,最大输出流量可达2.7 L/min。
A dual magnetostrictive axial plunger pumps-based electro-hydrostatic actuator(DMAEHA)is designed,and a new type of active rectification valve is proposed in this paper.The electro-hydraulic actuator driven by dual magnetostrictive axial plunger pumps can output bidirectional continuous displacement.Through the establishment of the mathematical model of the DMAEHA,it can be find that how the motor speed and the pipeline affects the output characteristics of the hydraulic cylinder.The experimental platform is built to test and verify the flow output characteristics of the DMAEHA at the same space and different phase angles.Through the comparison between the model analysis and the experiment results,the output characteristics of DMAEHA with different pipeline lengths are predicted.The experimental results show that the maximum output flow can reach 2.7 L/min at 180 Hz.
