摘要
采用有限元方法和MSC NASTRAN软件 ,建立了某型号再入飞行器的动力学分析模型。根据再入飞行器的脉动压力环境和随机振动分析理论 ,计算了某型号再入飞行器脉动响应加速度的均方根值和功率谱密度曲线 ,其数值计算结果与试验结果比较一致。
A dynamic analysis model for reentry vehicle is established by means of finite element method and MSC/NASTRAN software system. Based on fluctuating pressure environment hand random vibration theory, Fluctuating Response analysis of certain Reentry Vehicle is completed. Meanwhile, the RMS and PSD of acceleration response are presented, and the numerical results are consistent with the experimental results.
