卫星污染传输仿真模型及其应用研究

摘要

针对卫星污染环境地面模拟试验耗时长,成本高且工艺复杂等问题,开展卫星污染仿真研究.污染传输建模与分析是卫星污染仿真的关键,基于广域污染数值模拟理论,对热真空环境模拟试验中直接视角范围的分子污染传输机制进行了研究,在此基础上建立了相应的卫星污染传输仿真数学模型,利用Gauss数值积分方法对建立的卫星污染传输仿真数学模型进行了数值求解.实际工程表明:基于卫星污染传输仿真模型的数值求解结果与实际试验情况相吻合,从而验证了直接视角范围内的卫星污染传输仿真模型的可靠性.%Due to the long period,the high cost,and the complex techniques,the satellite contamination environment simulated test is very difficult.The satellite contamination transmission simulation model is very important to the satellite contamination environment simulated test.Based on the global region contamination simulation theory,the satellite molecular contamination transmission mechanism in direct lineof sight in the thermal vacuum environment test was researched,and the satellite contamination transmission simulation model was built and solved by Gauss numerical integration method.The simulation results were consistent with the actual test,and the reliability of the satellite contamination transmission simulation model were validated by the corresponding simulation results.
