摘　　要：基于火箭建模理论,结合某型火箭数据,建立了Matlab/Simulink环境下的新型箭体模型,并对建立的箭体模型进行仿真验证。将箭体模型按物理意义划分为动力学模型、推力模型、质量模型、重力模型和气动力模型,在Windows操作系统及Lab View_RT实时系统环境下,分别进行模块仿真验证,形成了通用箭体仿真模块库。以搭建的箭体模型为基础,开发了基于Veristand/Lab View_RT半实物仿真平台。型号实测数据对比结果表明:搭建的新型箭体模型正确且有效,可为多型号火箭提供通用箭体仿真模块库。Based on the rocket modeling theory and the data of a rocket,a newtype rocket body model was established in Matlab/Simulink environment. The established rocket body model was verified by simulation. According to the physical meaning,the rocket body model is divided into dynamics model,thrust model,quality model,gravity model and aerodynamics model. In the Windows operating system and LabView_ RT real-time system environment,all of the models were verified by simulation respectively. The general rocket body simulation module library was formed. Based on the established rocket body model,the semi-physical simulation platform of Veristand/LabView_RT was developed. It is shown that the model is correct and available compared with experimental data,providing common simulation modules for rocket models.
