摘　　要：文中的研究对象是一种弹载射流驱动机构,该驱动机构的输入是高压射流(高压燃气),其输出是推动力。通过检测驱动机构工作过程中的推动力变化,利用系统辩识和数字信号处理的技术,为驱动机构建立了数学模型,分析了瞬态响应过程,并给出了每次切换过程中的推力上升时间和输出稳定值的计算公式。This paper presents a transient response analysis of a jetting-flow-driving part which is used by a missile engine.This analysis is based on the data provided by a data acquisition system.By using system identification and digital signal processing approaches,the author obtained the mathematical model of the part being tested.And upon the model as well as some particular properties of the working conditions,the author also demonstrates the exact ways of data manipulation and formulas of calculating transient responses.

关 键 词：射流驱动 系统辩识 瞬态响应
