摘　　要：抗荷阀 -抗荷服系统的动态特性是决定其抗荷效果的关键指标。本文在理论分析和系统辨识研究的基础上提出采用 4极点、1零点、1延迟的线性模型作为机械式抗荷阀 -囊式抗荷服系统的动态特性模型 ,该模型的理论输出与实验数据符合甚好。给出了模型的一般型式 ,同时分析了气源压力、阀门安装角、抗荷服容积等系统结构参数对模型的影响。The dynamic response behavior is one of the most important factors of an anti g valve suit system. A linear model which includes four pole, four zero and one delay unit was developed in this paper to describe the dynamic response behavior of the valve g suit system. The parameters in the model were determined through a system identification method, and the agreement between model prediction and experimental result was satisfactory. The influences of system structural parameters such as source pressure, suit volume and valve angle were also discussed.
