| 摘 要： | 本文用MSC／NASTRAN软件完成了板壳组合结构在随机面分布力作用下的响应分析研究，并与实验结果作了比较。在确定载荷、建立动力计算模型和模态阻尼比取值等方面进行了较详细的研究，得到了令人满意的结果：典型点加速度响应均方根值的计算结果与实验结果相近，误差低于15％。

| Abstract: | In this paper,The response analysis of the structure composed of plates and shells at random pressure by MSC/NASTRAN has been completed ,and compared with experimental results.Determing of load,establishing of dynamic computing model and determing of modal damping have been discussed in detail.The comparision between analysis and experiment shows good agrement:the computing RMS values of acceleration at tipycal places are closed to experimental data,with a error of less than 15%. |
