Topology optimization for structural mass reduction of direct drive electric machines
TL;DR: In this article , the rotor of a 5 MW wind turbine generator was analyzed to determine geometric avenues of mass reduction with varying safety factors, and three designs were created with safety factors between 1 and 2 which resulted in structural mass reductions ranging between 54%-67% compared to a baseline design leading to a 13%-25% increase in power density.
Journal ArticleDOI
Schwarzites and schwarzynes based load-bear resistant 3D printed hierarchical structures
TL;DR: In this article , the authors proposed and tested a new approach to create hierarchical porous structures, in which the mass density varies from the center to the borders, i.e., a radial gradient.

Machine Learning based Lattice Generation Method derived from Topology Optimisation
Jie Wang,Ajit Panesar +1 more
TL;DR: In this paper , a neural network-based inverse lattice generator is trained to output lattice unit cells from the input of target mechanical properties, and the proposed ML-based lattice generation method utilises the density distribution and stress field of low-resolution Topology Optimization (TO) design to inform the inverse generator and produce lattice cells.
Journal ArticleDOI
Design and manufacturing of graded density components by material extrusion technologies
TL;DR: In this article , the authors proposed a method for fabricating graded density shell-based lattice structures for MEX technology by using the infill patterns available in the CAM software and editing the G-code based on a density map defined by volumetric models.
Journal ArticleDOI
Investigation of wear properties of 3D-printed PLA components using sandwich structure – A review
Madheswaran Subramaniyan,Sivakumar Karuppan,Keshav Radhakrishnan,Radhakrishnan Rajesh Kumar,K. Saravana Kumar +4 more
TL;DR: In this paper , the use of composite material in FDM machines enhances the tribological strength of printed components above tribological improvement by altering machine control parameters, and the wear strength of 3D printed specimens is improved by the uniform distribution of composite materials in the feedstock filament.

Fronts propagating with curvature-dependent speed: algorithms based on Hamilton-Jacobi formulations
Stanley Osher,James A. Sethian +1 more
TL;DR: The PSC algorithm as mentioned in this paper approximates the Hamilton-Jacobi equations with parabolic right-hand-sides by using techniques from the hyperbolic conservation laws, which can be used also for more general surface motion problems.

Generating optimal topologies in structural design using a homogenization method
Martin P. Bendsøe,Noboru Kikuchi +1 more
TL;DR: In this article, the authors present a methodology for optimal shape design based on homogenization, which is related to modern production techniques and consists of computing the optimal distribution in space of an anisotropic material that is constructed by introducing an infimum of periodically distributed small holes in a given homogeneous, i.i.
