相机在从地面到太空的过程中,需要经历重力、温度、气压、辐射等多种环境因素的变化,而这些因素都可能导致空间相机分辨率下降、像质变坏、功能失效甚至系统破坏。所描述的系统工作于18±15℃的温度环境,要求光学反射镜在30℃温度变化范围内仍能正常成像。经优化设计,应用计算机仿真手段进行了静、动态及热特性的分析,提出了一种采用中心粘接结合Bipod柔性支撑形式,解决了在大跨度环境温度范围下的反射镜结构支撑问题。
Camera from ground to space in the process, you need to experience gravity, temperature, pressure, radiation and other environmental changes, and these factors may lead to the decline in space camera resolution, image quality deterioration, failure or even system damage. The described system operates at a temperature of 18 ± 15 ° C and requires that the optical mirror still image normally at a temperature of 30 ° C. Based on the optimized design, the static, dynamic and thermal characteristics of the Bipod are analyzed by computer simulation. A new type of Bipod flexible support is proposed, which solves the problem of supporting the mirror structure under long-span ambient temperature range.
