为了研究车载导弹武器系统中关键构件柔性变形对导弹发射的重要影响,应用刚柔耦合动力学理论,在虚拟样机软件ADAMS中建立车载导弹刚柔耦合动力学模型。采用有限元和Beam梁理论分别建立柔性体模型,将其导入ADAMS中完成装配。通过对仿真结果的对比分析,得到了两种柔性体对导弹初始姿态和离轨参数的影响规律。结果表明利用有限元建立的柔性体精度更高,更符合研究需要。

In order to study the important influence of flexible deformation of key component in vehicular missile weapon system on missile launching, the rigid-flexible coupling dynamics model of vehicular missile was built in virtual prototyping software ADAMS by using the rigid-flexible coupling system dynamics theory. The flexible body model of key component was set up by adopting finite element and Beam theory, and it was imported into ADAMS to complete assembly. Through the comparison and analysis of simulation results, the influence rules of two kinds of flexible body to missile initial attitude and deorbit parameters were achieved. The results indicated that the flexible body built by finite element(FEM) technique was more accurate and suitable for research needs.
