摘要
为分析液压支架用大流量液控单向阀流固耦合情况,采用Pro/Engineer软件对一级、二级阀芯及阀体三维造型,采用ICEM-CFD软件对阀内流道进行网格划分,采用CFX软件进行两种开启形式下的液控单向阀内部全流场定常数值计算,得出各自工况下的速度矢量图.利用ANSYS Workbench软件对液控单向阀内部流场和液控单向阀阀芯及阀体进行单向流固耦合计算,利用ANSYS后处理工具得到两种工况下阀芯及阀体的应力云图并计算出阀芯所受支反力大小.结果表明:液控单向阀反向开启时为危险工况,乳化液在控制杆卸压槽处流速最大,一级、二级阀芯应力最大,得出反向开启时,控制压力为19.1 MPa.
This paper built the primary and secondary valve core and valve body three-dimensional model by using Pro/Engineer software and meshing the inside flow channel by the ICEM-CFD sottware. CFX software was used to calculate two kinds of open type unsteady in hydraulic controlled check valve. Using CFX software and ANSYS Workbench software, this study calculated the fluid-structure interaction of flow field of hydraulic controlled check valve and hydraulic control one-way valve core and valve body. Two kinds of working conditions of valve core stress nephogram and reaction force were obtained by using ANSYS workbench post-processing tools. The results show that when the hydraulic controlled check valve reverse open, primary and secondary stress reaches its maximum, emulsion in the control rod unloading slot flow velocity is the largest, and the pressure of control is 19.1 MPa.
