| 摘 要： | 在考虑结构弹性变形、空间大范围相对运动，以及弹性运动与刚体运动耦合的基础上，建立了运载火箭整流罩的有限元分析模型。采用MSC．NASTRAN和ADAMS软件仿真模拟了新一代大运载火箭整流罩不同设计方案的地面分离，并与试验结果进行了比较。分析表明，整流罩的多个仿真模拟分离参数与试验值较为接近，证明本文的整流罩抛罩多体动力学仿真方法有效。

| Abstract: | The model of finite element analysis for fairing of launch vehicle was established based on the factors of the structural elastic deformation and large-scale space relative movement as well as coupling of elastic and rigid movement in this paper, The separation simulation of different fairing designed of new generation launch vehicle by means of MSC. NASTRAN and MSC, ADAMS software was computed, and compared with the ground test result, The analysis results showed that the various separation parameters simulated of fairing were similar with those gained in the ground test. It was proved that simulation of multibody dynamics for the fairing separation was effective, |
