摘　　要：滑阀的流量特性直接影响伺服阀的性能。使用Fluent软件对滑阀在不存在棱边圆角(理想滑阀),棱边圆角分别为5μm、8μm和10μm等4种情况进行数值仿真研究,得出棱边圆角对滑阀流量特性的影响规律,并对理想滑阀的流量系数进行了修正。The flow characteristic of the spool valve affects the performance of the servo valve. U- sing Fluent, this paper discusses the following four cases： the ideal spool valve, the spool valves with arris-edge fillets of 5, 8 and 10 μm. The effects of different fillets on the valve＇ s flow characteristics are discussed and a correction formula for the flow coefficient of ideal spool valve is proposed by polynomial approximation of the simulation results.
