空间光学镜筒是一个典型的圆筒形薄壳结构,而圆筒形薄壳在航空、航天等机械领域得到了广泛的应用,为减轻薄壳质量、提高薄壳强度和提高其制造工艺性,通常的圆柱形薄壳都具有加强筋,很显然,加强筋使薄壳的强度及制造工艺性大大提高。但是,加强筋使空间光学镜筒的动力学特性如何变化,至今还没有被深入的探讨。本文对航天相机中筒处的具有轴向和径向加强筋的圆筒进行动力学分析,研究加强筋对空间光学镜筒动力学特性的影响。
Space optical tube is a typical cylindrical thin shell structure, and cylindrical thin shell in the aviation, aerospace and other mechanical fields have been widely used in order to reduce the shell quality, improve the shell strength and improve the manufacturing process of , The usual cylindrical shell has a stiffener, it is clear that the stiffener greatly enhance the strength and manufacturing process of the shell. However, how the stiffeners change the dynamic characteristics of the space optical lens barrel has not been explored yet. In this paper, the dynamic analysis of the cylinder with axial and radial stiffeners in the space camera was carried out to study the influence of stiffeners on the dynamic characteristics of the space optical tube.
