Abstract High performance of the spacecraft structure is required in
the special environment, it includes mechanical performance and
operational performance, etc. When performing tasks, the
spaceborne equipment requires high precision. Therefore, the design
of lightweight, high stability and high reliability structure is essential
for spacecraft. Topology optimization is widely used in structural
design. However, there are some problems in the structure after
macro topology optimization, such as checkerboard, local optimal
solution and other phenomena. Despite a long calculation period, the
obtained structure is often not smooth enough and hard to
manufacture. Aiming to this issue, this paper proposes a combined
method… More >
