| 摘 要： | 采用解析方法,分析了薄壁板结构在热载荷与噪声联合作用下的响应特性;依据薄板的大挠度非线性理论,采用以基频响应为主的单自由度模型,推导出了具有温度影响的非线性运动方程,并利用等价线性化方法将该方程线性化,在此基础上得出了应力响应的统计特性。

| Abstract: | The response characteristics of thin-wall panel structure with the combined actions of thermal load and noise were analyzed by adopting analytic method.Nonlinear motion equation with temperature influence was derived using the single freedom module focused fundamental frequency response according to nonlinear theory of large deflection,and the nonlinear equation was linearized by the equivalent linearization method,then based on linearization equation the statistic characteristics of stress response were obtained. |
