摘要
为了保证舱门机构具有高的静态结构刚度、优良的动态结构性能,研究了自然界中脉动风的风谱及其数值模拟方式,介绍了采用风速功率谱密度方法进行随机风载分析的过程,建立了一个舱门打开状态的完整计算模型,分析了舱门在静态风载和动态风载下的位移响应。结果表明动态风载响应约为静态风载响应的40.8%,研究结果为该型飞机舱门的设计提供了一定的理论依据。
In order to ensure that the door mechanism has high static structural stiffness and excellent dynamic structural performance.The wind spectrum and numerical simulation of fluctuating wind in the nature were studied,wind power spectral density method was introduced in the process of random wind load analysis, and a calculation model of the door in the open position was established, The displacement response of door was analyzed under the static wind load and dynamic wind load.The result show that the dynamic wind load response is about 40.8% of the static wind load response.This research could provide a certain theoretical basis for this type of door design.
