The flow control servovalve modeling methods in hydraulic system simulation were discussed,focusing on the principle of description method based on sample data of flow control servovalve. A physical simulation model was established by Simhydraulics software. It provides base for improving the accuracy of hydraulic servo system simulation.%对电液流量伺服阀在液压伺服系统仿真分析中的建模描述方法进行了探讨，重点对基于流量伺服阀样本数据的描述方法进行了原理阐述。采用Simhydraulics软件搭建了物理测试模型并进行了建模验证，为建立高精度液压系统物理仿真模型奠定了基础。
