| 中文摘要: |
| 为了提高喷气织机的引纬性能，降低能耗，课题组设计了一种基于压电陶瓷驱动的高频喷射阀。首先对喷射阀的核心部件压电弯曲片的刚度性能做了仿真分析和理论验证；然后对压电陶瓷驱动型高频喷射阀进行FLUENT模拟仿真；最后利用MATLAB软件对压电驱动系统进行动态仿真，确认了合理的工作间隙，进而对喷射阀的结构进行了优化。模拟得到最佳工作参数：喷射阀进气口直径为4 mm，压电喷射阀的工作间隙为1.5 mm。设计的这种喷射阀响应时间相比传统电磁式喷射阀缩短了60%，大大降低了气能损耗。 |

| In order to improve the weft insertion performance of the air jet loom and reduce energy consumption, a high frequency injection valve driven by piezoelectric ceramics was designed. Firstly, the rigidity performance of the piezoelectric bending sheet, a core component of the injection valve, was simulated and verified. Secondly, the FLUENT simulation of the piezoelectric ceramic driven high frequency injection valve was performed. Finally, the dynamic simulation of the piezoelectric driving system was performed by using MATLAB software. The reasonable working gap was confirmed, and the structure of the injection valve was optimized. The optimum working parameters were obtained that the inlet diameter of the injection valve was 4 mm and the working gap of the piezoelectric injection valve was 1.5 mm. The response time of this injection valve is 60% shorter than that of the traditional electromagnetic injection valve, which greatly reduces the gas energy loss. |
