Stiffness Optimization Design for Cellular Materials Designed for TPMS

Icro Meattini

The distinctive topology-driven skillfulness of natural biological systems has intended the fabric science analysis community to style and synthesize architected cellular materials for various engineering disciplines. However, the lattice cell style of architected cellular materials is extremely discretionary, creating the planning of architected cellular materials terribly troublesome. so as to beat these issues, associate degree innovative triple amount lowest surface (TPMS) lattice kind distribution rule supported the most strain energy principle is planned during this paper to optimize the stiffness of the structure. The rule establishes the mapping relationship between the denseness of TPMS lattice cells and also the surface bias parameter t by generating a voxel model, obtains the equivalent mechanical properties of lattice cells as a perform of denseness by homogenization rule and performance fitting,establishes a TPMS lattice info, and innovatively distributes the TPMS lattice sorts by choosing the most strain energy lattice cells on the premise of the topology optimization results. The experimental results show that the stiffness of the multi-TPMS lattice structure is improved by fifty five.89% and 30.15%, severally, compared with the 2 single lattice structures.
