摘要
风载荷是导弹发射装置结构设计中的重要设计载荷,大型导弹由于长度较大、具有大长细比,因此其发射装置在起竖后受到风载荷的影响较大。分析了自然风的组成和特性,应用随机振动理论分别研究了平均风和脉动风对导弹发射装置起竖后的影响作用,建立数学模型并用Matlab软件模拟仿真了发射装置产生的位移响应,为该型导弹发射装置的设计提供了一定的理论依据。
Wind load is very important in the structure design of missile launching device. Some large missile has large length and large slenderness ratio, so the missile launching device is under the se- rious influence of wind load when it is erected. The composition and properties of the wind load are ana- lyzed and the impact by the average wind and fluctuating wind on missile launching device is studied with the random vibration theory. Matlab software is used to establish the mathematical model and simulate the displacement response produced by the launcher, so this research provides useful information for the de- sign of the missile launching device
