摘要

为了实现模块化微纳卫星快速装配和试验，采用了虚拟装配与试验技术，对微纳卫星的模块化设计、装调、试验、典型边界条件和工况进行了研究。首先，对微纳卫星虚拟装配的特点和技术流程进行了归纳研究，并采用三维造型软件开发设计了快速组装系统，实现卫星模型的质量特性分析和干涉检查；其次，针对微纳卫星快速构建理念，将卫星力/热模型各个部件均按照标准模块形式进行简化建库，并完成模型修正；最后，以某型微纳卫星研制为例，采用Patran/Nastran、AutoCAD/ThermalDesk软件平台，利用局部物理试验、低载荷物理试验等方法在计算机上模拟卫星总体结构在真实实验工况及边界条件下的动力学特性/热平衡特性及响应情况。研究表明，虚拟装配与试验技术对卫星总体的优化设计和试验过程中条件的制定具有重要的参考价值。通过虚拟试验技术的使用可将总体开发周期缩短30~50%，研制成本降低30%左右，可满足目前我国微纳卫星发展"多"、"快"、"好"、"省"的发展需求。

Abstract

In order to realize objective of rapid assembly and experiment for modal micro/nano-satellite

Virtual assembly and experimental technology were adopted. Modal design

rigging

experiment and condition and working condition of typical interface of micro-nano satellite were researched. Firstly

characteristic and technical process for Virtual assembly of micro/nano-satellite were provided with conclusion research

and rapid assembly system was developed and designed by taking advantage of 3D modeling software to realize quality characteristic analysis and intervention inspection of satellite modeling. Secondly

aimed at rapid construction concept of micro-nano satellite

all parts of satellite power/thermal model were provided with simplified database-creating according to standard module form

and model updating was completed. Finally

taking development for some micro-nano satellite as example

based on Patran/Nastran and AutoCAD/ThermalDesk software platforms

dynamic characteristic/heat balance characteristic and response of overall structure for satellite under actual experimental working condition and boundary condition were stimulated by adopting methods for local physical experiment and low-load physical experiment etc. on computer. It shows in research that Virtual assembly and experimental technology have important reference value to overall optimization design and condition formulation during the process of experiment of satellite. Through use of Virtual experiment technology

overall development period can be shortened by 30%-50%

and development cost can be lowered by about 30%

which can meet development requirements for "more"

"rapid"

"good" and "saving" of micro-nano satellite in our country.
