Based on these models,physical principles behind imaging effects of defocused blur,motion blur and asterism were analyzed thoroughly,and methods to simulate these effects were proposed as well.

Vibration response sensitivity analysis for satellite structures;

The satellite structure is very crucial to the constrains of the weight and deformation due to its special operation environment.

This paper expounds that the carbon fiber composite material has become themain structural material for satellites, Reviews the applications of composite for satellites athome and abroad, further illustrates that the adoption of composite for satellite structures iseven more effective, raises the preliminary viewpoint for the development of compositetechnique for satellites.

Then,by using iterative constitution method of hierarchical network,an ideal constellation structure is proposed.

Based on the work moving character of the star wheel loading machine and the woking performance of the headroader and by force analysis to the star wheel loading machine,introduced the confirmation ways for the star wheel structure,the star wheel rotate speed and the power loading of the star wheel loading machine.
