【摘要】 从振动响应的基本理论出发,建立火箭弹有限元计算模型,通过模拟计算分析,对大长径比火箭弹在瞬态冲击扰动下的振动响应进行了研究,得到了一些有益结论,可为火箭弹的结构和强度设计提供一定依据。更多还原

【Abstract】 Based on the basic vibrating theory, the characteristical responses of the vibration of slender rockets are studied by using Finite Element Method in this article. Some significant conclusions are obtained with the analysis of the results of calculation. These can be considered as references for the design of rockets.更多还原
