摘要:
针对某型气动换向阀在研制过程中出现由于阀芯/阀座撞击变形导致阀芯卡死的现象，对阀芯/阀座的撞击特性进行了仿真研究，定量分析了撞击过程以及不同阀座高度对撞击特性的影响，根据仿真结果对换向阀进行了改进设计，试验结果表明改进后的换向阀满足使用要求。
Abstract:
The simulation research of impact characteristics of valve spool and valve seat in selector valve was carried out to eliminate the bind-seize phenomenon caused by impact deformation of valve spool and valve seat, which emerged in the development process of a selector valve. The process of impact between valve seat and spool, and the influence of different height on impact characteristics were analyzed quantitatively. The revised design for the selector valve was performed according to the simulation result. The test result shows that the improved selector valve can meet the operating requirement.
