    摘要:

    首先,根据一种出口型的制导武器气动舵机工作原理建立了舵机放大器、射流管阀、作动筒、反馈电位计等关键部件的数学模型;然后根据所建立的数学模型进行MATLAB/Simulink仿真,验证该模型在频域特性及时域特性的准确性;最后,针对制导弹药靶试过程中气动舵机出现的“毛刺”干扰问题,分别对舵机各关键部件数学模型注入“毛刺”干扰仿真,并与制导弹药靶试遥测数据进行对比分析。仿真结果表明,气动舵机反馈电位计故障可导致气动舵机出现“毛刺”问题,经实际排除后再次靶试“毛刺”干扰得到消除,为后续制导武器气动舵机故障模式分析提供了一定理论基础。

    Abstract:

    Firstly, the mathematical models of actuator amplifier, Jet Tube Valve, actuator, feedback potentiometer and other key components are established according to the operational principle of pneumatic actuator of an export-type guidance weapon Then MATLAB/Simulink simulation is carried out according to the established mathematical model to verify the accuracy of the model in frequency domain and time domain, in order to solve the problem of“Burr” interference in the pneumatic rudder during the target test of guided munitions, the mathematical models of the key components of the rudder are injected with“Burr” interference simulation respectively, and it is compared with the telemetry data of the target test of the guided ammunition. The simulation results show that the fault of pneumatic actuator feedback potentiometer can lead to the problem of“Burr”, and the“Burr” interference can be eliminated after the actual elimination, it provides a theoretical basis for failure mode analysis of pneumatic rudder of follow-up guidance weapon.
