CMGs will allow a small satellite to perform off-nadir pointing enable such spacecraft to collect more earth and space science data than before.
Topology optimization is often used during preliminary design cycles to find the optimal distribution of material in a given package space.
The fundamental problem in structural topology optimization is the determination of an optimal layout of material within a prescribed domain.

Fig.1 The geometric model of simple supported beam Description of geometric parameters of simply supported beam: The longitudinal dimension: L=0.726m The transverse dimension: B=0.04m The thickness dimension: H=0.007m Moment of inertia: Cross section: Description of some attribute parameters of simply supported beam: Material: 45# Density: Elastic modulus: The building and analysis of the discrete multi-freedom model The beam is equally divided into "N" sections in the longitudinal direction, assumed that the mass equally is concentrated on the joint of every two sections, so the mass of the beam is equally divided into "N-1" particles.

Lower compaction pressures resulted in a more permeable and therefore economical material.
On the other hand, materials with higher compaction pressures can retain smaller particles because they have smaller pores.
