| 中文摘要: |
| 针对流量阀功重比低、体积大的问题，提出一种新型二维插装式流量调节阀。阀体后端的力矩马达带动具有双自由度的二维活塞转动并进行功率放大驱动阀芯，阀体上的压差反馈杆可精准地测量进出口压差，无需安装额外的压力传感器。首先建立该阀的数学模型，并使用Matlab进行了稳定性分析；其次以AMESim为平台搭建了模型，对其动静态特性进行了仿真分析；最后进行实验验证。该阀滞环为4.4%，线性度为1.6%，响应时间约为44ms，幅频宽约为17Hz，相频宽约为28Hz，压差测量范围为8MPa。理论分析和实验结果均表明，二维插装式流量调节阀不仅结构简单、功重比高，且具有良好的动静态特性，是较为合适的解决方案。 |

| A novel two-dimensional cartridge flow control valve is proposed to address the problems of low power-to-weight ratio and large size of flow valves. The torque motor at the back of the valve body drives a two-dimensional piston with two degrees of freedom and amplifies the power to drive the spool movement, and the differential pressure feedback lever on the valve body can accurately measure the inlet and outlet pressure difference without installing additional pressure sensors. In this paper, the mathematical model of the valve is firstly established, and the stability analysis is carried out by using Matlab. Then the model is built by using AMESim, and the dynamic and static characteristics are simulated and analyzed. Finally, it is verified by experiment. This valve have a hysteresis loop of 4.4%, linearity of 1.6%, response time of about 44ms, amplitude frequency width of about 17Hz, phase frequency width of about 28Hz, and the pressure difference measurement range is 8MPa. Both theoretical analysis and experimental results show that two-dimensional cartridge flow control valve is a suitable solution not only for its simple structure and high work-to-weight ratio, but also for its good dynamic and static characteristics. |
