Modeling and simulation of flow field of main spool in servo valve

摘要

The Servo valve is a core component of servo control system. Its characteristics would directly affect the entire performance of servo control system. In this paper, Fluent is used on the main spool internal flow simulation when its opening is fixed. The valve flow characteristic is analyzed. The simulation result is consistent with the laws of fluid flow and the theoretical. It provides a basis for optimal design of electro-hydraulic servo valve.
