基于AMESim与Simulink的反后坐装置结构仿真分析

为解决传统火炮反后坐装置难以控制后坐阻力,得到理想后坐阻力规律,提出用液压伺服阀辅助调节控制反后坐装置的后坐阻力规律。在节制杆式制退机的基础上,采用AMESim与Simulink软件进行联合仿真,建立阀控反后坐装置的仿真模型,结合灰色预测模糊控制算法,分析了不同伺服阀开口大小和延时时间对后坐阻力的影响。结果表明:合适的伺服阀开口大小能有效减小后坐阻力,得到理想后坐阻力规律;延时时间会使控制效果减弱,采用灰色预测模糊控制算法能尽可能减小伺服阀延迟时间对后坐阻力规律影响。

Simulation Analysis Based on AMESim and Simulink for Recoil System

In order to solve the problem that a traditional artillery recoil system is difficult to control recoil resistance and get the ideal recoil resistance law, a hydraulic servo valve is used to adjust and control the recoil resistance of recoil system. On the basis of control rod type retracting machine, a simulation model of the softwares AMESim and Simulink is used to establish a simulation model of valve-controlled recoil system. Combined with gray prediction fuzzy control algorithm, the impact of different servo valve opening sizes and delay times on recoil resistance is analyzed. The results show that the appropriate size of servo valve opening size can effectively reduce the recoil resistance and obtain the ideal recoil resistance law; the control effect will be weakened by delay time, and we can minimize the influence of servo valve delay time on recoil resistance law by using the grey predictive fuzzy control algorithm.
