ZHANG Wei, GUAN Gong shun, PANG Bao jun, ZOU Jing xiang (Dept. of Astronautics Engineering and Mechanics, Harbin Institute of Technology, Harbin 150001,China)  
In order to avoid impact by meteoroid and space debris at high velocity and to ensure safety of a spacecraft, a Nysmith model is proposed to predict the shielding performance of a protective structure, and the effect of impacting conditions and structure parameters on optimal results is analyzed using a nonlinear optimization method. The relationship between existence of feasibility conditions for global optimal solution to bumper/back wall spacing and impact parameters is obtained. The effect of all parameters on optimal results is shown in the figures.
