为准确拟合坦克随动系统的动态特性,优化综合性能,获得更好的控制跟踪效果,建立了坦克随动系统轴间耦合负载非线性动力学数学模型、方位子系统驱动端数学模型、俯仰子系统驱动端数学模型。采用基于Modelica语言的仿真软件Mworks建立坦克随动系统的仿真模型库,并进行仿真研究。结果表明:基于Mworks建立的模型能够准确地对坦克随动系统进行仿真验证,稳定精度满足坦克随动系统的要求;基于Mworks的坦克随动系统建模简便、直观,随动系统间的复杂关系可通过Mworks中各子模块直接建立,且建好的坦克随动系统综合动力学模型重复利用性好,提高了建模效率。

In order to accurately reflect the dynamic characteristics,optimize the comprehensive performance and obtain better control tracking effect for tank servo systems,the mathematical model of the nonlinear dynamics of the coupled load between the axles,the mathematical model of the drive end of the azimuth subsystem,and the mathematical model of the drive end of the pitch subsystem,were established.Simulation software Mworks based on Modelica language was used to establish the simulation model base of the tank servo system,and the simulation research was carried out.The results show that the model based on Mworks can accurately simulate and verify the tank servo system,and it can meet the requirement of stable precision of the tank servo system.Based on MWorks,the tank servo system can be intuitively simply modeled,and the relationship between modules directly reflects the relationship between physical quantities.The established comprehensive dynamic model of the tank servo system has good repeatability,which improves the modeling efficiency.
