摘要
选取圆柱壳结构作为研究对象 ,针对圆柱壳结构特征 ,提出采用有限条法建立圆柱壳结构的动力学模型 ,基于该模型 ,采用模态叠加法计算其动态响应 ,运用双模态叠加法计算响应灵敏度 ,并对计算结果进行了相应的分析 .
A cylindrical shell is selected as an examined object. According to the features of the cylindrical shell, the finite stripe method is adopted to establish the dynamics model of the cylindrical shell. Based on the finite stripe model, the mode superposition method is used to calculate its dynamic response, and the double mode superposition method to calculate its sensitivity of dynamic response. The results are analyzed correspondingly.
