【摘要】：安全阀在保证井下煤矿安全生产方面有着不可言喻的重要性。鉴于安全阀的使用条件、工作状态以及系统介质的复杂因素,将流体动力学分析软件FLUENT和三维建模软件CATIA等相结合进行仿真分析,研发出高质量、高标准的大流量安全阀,为保证液压支架系统的稳定工作和煤矿的安全生产都有着一定的现实意义。本文所针对研究对象为液压支架用德国进口安全阀,介绍了其结构与工作原理,并且对安全阀的静态分析得出一些重要的仿真参数。利用仿真软件AEMSim对其进行动态特性分析,并绘制了压力曲线图和阀芯位移曲线图,找到了影响其性能优劣的一些关键因素;然后采用WORKBENCH软件把在CATIA基础上建好的安全阀三维模型的三维流体模型抠出来并利用ICEM进行网格划分,最后倒入流体动力学分析软件FLUENT对其进行仿真,绘制出其在不同边界条件下、不同开口度下的总压云图、动压云图、速度云图以及速度矢量图,通过比对分析结果所得到的结论,可为以后安全阀的设计工作提供一些参考。
[Abstract]:The safety valve has the indescribable importance in ensuring the underground coal mine safe production. In view of the operating conditions, working state and complex factors of the system medium, the hydraulic dynamic analysis software FLUENT and the 3D modeling software CATIA are combined to simulate and analyze the safety valve, and a high quality and high standard large flow safety valve is developed. In order to ensure the stability of hydraulic support system and the safety of coal mine production has certain practical significance. The structure and working principle of German imported safety valve for hydraulic support are introduced in this paper, and some important simulation parameters are obtained by static analysis of safety valve. The simulation software AEMSim is used to analyze its dynamic characteristics, and the pressure curve and valve core displacement curve are plotted, and some key factors affecting its performance are found. Then WORKBENCH software is used to extract the three-dimensional fluid model of the safety valve built on the basis of CATIA, and ICEM is used to mesh it. Finally, the fluid dynamics analysis software FLUENT is poured into the software to simulate it. The total pressure cloud map, dynamic pressure cloud map, velocity cloud map and velocity vector diagram under different boundary conditions and different openings are drawn. The conclusions obtained by comparing the analysis results can provide some references for the design work of the safety valve in the future.
