SW shield has shown the superior performance compared with the other three structures for protecting spacecraft from meteoroid and orbital debris(M/OD)at an equal areal density and the same imp.

The software of design optimization on orbital debris shielding structure has been initiated in the world on the basis of orbital debris assessment software.

For the spacecraft shading problem in orbital debris risk assessment, based on Roberts algorithm and Z-buffer algorithm, a shading algorithm is proposed, which is simple in computation, accurate in results and versatile in applications.

Modeling and simulation of collision probability between flying warheads and space debris;

Performance analysis for spacecraft shield structures against meteoroid and space debris;

Calculation of Lamb wave in acoustic emission and application in monitoring impact from space debris;

Debris population estimation is an important task in statistical characterization of space debris environment, and is of great significance for validation of space debris environment models, assessment of impact risk to spacecrafts and prediction of the long-term growth potential of the number of debris.
