Abstract: Topology optimization methods of compliant mechanisms are
presented. Firstly, the ground structure method and the homogenization
method are discussed. The models of optimization are obtained. Two
material models are discussed for the homogenization method. Secondly,
the extraction process and two filter algorithms are presented. One of
the algorithm is based on the calculation of the element filter density,
the another one is based on the calculation of the nodal density. The
former is valid for post process, and the latter is valid in the design
process. Finally, the key problems need to be solved in the field are
pointed out.
Key words: Compliant mechanism Topology optimization Ground
