摘　　要：介绍了双喷嘴挡板电液伺服阀的结构组成、工作原理和性能特点,通过数学建模获得了静、动态压力特性方程,通过试验测得了该阀压力-电流静态特性、阶跃响应和频率响应曲线。理论分析和试验结果表明:双喷嘴挡板电液伺服阀具有良好的静态压力-电流比例特性,动态响应快。Structural composition, work principle and performance features of a dual injector baffle electro-hydraulic servo valve are described in the article. Static and dynamic pressure characteristic equations are obtained through mathematic model establishment. Static characteristic curve of pressure vs. current, step response curve and frequency response curve are obtained form tests. The theoretical analysis and tests result show that the dual injector baffle electro-hydraulic servo valve features excellent proportional characteristic of static pressure vs. electric current and high dynamic response.
