【摘要】:為提高設(shè)計(jì)效率提出了一種空間光學(xué)遙感器柔性支撐參數(shù)化設(shè)計(jì)方法。分析了溫度變化、裝配誤差兩種工況下對柔性支撐形變的需求。并根據(jù)折衷規(guī)劃理論設(shè)置柔性支撐的優(yōu)化函數(shù),以某空間光學(xué)遙感器主鏡所用柔性支撐為例給出柔性支撐參數(shù)化設(shè)計(jì)的詳細(xì)設(shè)計(jì)過程。經(jīng)過參數(shù)化設(shè)計(jì),主鏡柔性支撐基頻達(dá)到88.8Hz,溫度變化4℃,鏡面的均方根(RMS)達(dá)到5.3nm,0.1mm裝配誤差下的鏡面RMS達(dá)到12.9nm,光軸水平1g重力鏡面RMS達(dá)到5.0nm。柔性支撐的性能顯著提高并且所有設(shè)計(jì)滿足指標(biāo)。同時(shí)設(shè)計(jì)過程實(shí)現(xiàn)了計(jì)算機(jī)自動化設(shè)計(jì),大大減少了人力投入,縮減了設(shè)計(jì)周期。
[Abstract]:In order to improve the design efficiency, a parametric design method for flexible support of space optical remote sensor is proposed. The requirements of flexible bracing deformation under temperature change and assembly error are analyzed. According to the eclectic programming theory, the optimization function of flexible support is set up, and the detailed design process of flexible support parameterization is given by taking the flexible bracing used in the primary mirror of a space optical remote sensor as an example. Through parameterized design, the fundamental frequency of flexible support of primary mirror reaches 88.8Hz, the temperature changes at 4 鈩,
