“…(2016) studied the static stability of the Voronoi grid structure and concluded that the Voronoi grid structure is not only aesthetically pleasing but also statically efficient. Froli and Laccone (2017) carried out experimental research on a free‐form Voronoi grid structure and confirmed that the Voronoi diagram is an effective grid for spatial grid structure. The Rokko Mountain Observatory in Japan is also designed according to the Voronoi diagram (Su, Wu, Qiao, & Shen, 2019).…”

Free‐form grid structures have developed increasingly with the development of computer‐aided design and advanced construction technology. However, the grid generation is still a difficulty for designing free‐form grid structures. The computational morphogenesis of free‐form grid structures with the Voronoi diagram is proposed to solve this difficulty. Voronoi diagram is introduced to form the irregular grid of structures. Morphologies of plane and curved surface Voronoi grid structure are formulated to realize parametric modeling of the structural grid. A comprehensive structural index is proposed for evaluating free‐form grid structures quantitatively from the aspects of both architectural and structural behaviors. Taking the seeds as optimization variables and the comprehensive structural index as optimization objective, the grid generation problem is transformed into an optimization problem. Numerical examples show that the proposed morphogenesis is feasible and effective for the grid generation of free‐form structures. The free‐form grid structures generated by the proposed method have not only appealing geometry but also good mechanical behavior. The consideration of the symmetry can accelerate the grid generation process. Different grid distributions can be realized with different supports.

“…In Figure 18, many planar coil designs for WPT systems are depicted, including rectangular, circular, and hybrid forms. These are applied to boost output and fix transmitter and receiver misalignment problems similarly to structural issues [314]. Additionally, each model's associated benefits and drawbacks are listed in a similar table [315].…”

Electric vehicles could be a significant aid in lowering greenhouse gas emissions. Even though extensive study has been done on the features and traits of electric vehicles and the nature of their charging infrastructure, network modeling for electric vehicle manufacturing has been limited and unchanging. The necessity of wireless electric vehicle charging, based on magnetic resonance coupling, drove the primary aims for this review work. Herein, we examined the basic theoretical framework for wireless power transmission systems for EV charging and performed a software-in-the-loop analysis, in addition to carrying out a performance analysis of an EV charging system based on magnetic resonance. This study also covered power pad designs and created workable remedies for the following issues: (i) how power pad positioning affected the function of wireless charging systems and (ii) how to develop strategies to keep power efficiency at its highest level. Moreover, safety features of wireless charging systems, owing to interruption from foreign objects and/or living objects, were analyzed, and solutions were proposed to ensure such systems would operate as safely and optimally as possible.

“…Inspired by lightweight and robust lattice structures that appear in nature, some works addressed the use of a Voronoi mesh for structural purposes at a larger scale. The works Froli & Laccone, 2017;Pietroni et al, 2015;Tonelli et al, 2016 proposed and validated a method for generating a Voronoi mesh, whose cells conform to the principal stress directions of the underlying surface, and are scaled and stretched accordingly. Su et al (2020) developed a morphogenesis method for Voronoi structures of high architectural and structural performances.…”

In the context of tall building design, the tube concept represents one of the most performing systems. The diagrid is the widespread type of tube system and consists of a diagonal grid of beams that wraps the building, forming a diamond pattern. It performs as lateral bracing and is additionally able to sustain vertical loading through axial forces. Despite its efficiency, a growing interest is recently observed in alternative geometries to replace the diagrid pattern and improve the architectural impact conferred by the building skin aesthetics on the urban environment. The paper pursues the use of a Voronoi mesh, in which the geometry of the cells is steered to known schemes for the structural design of a cantilever tube structure. The objective is to mimic a macroscopic structural behavior through a topology and size modification of the Voronoi mesh that increases the density for creating resisting paths with higher stiffness. The paper proposes a novel method Vorogrid for designing a new class of tall buildings equipped with an organiclooking and mechanically sound tube structure, which makes them a valuable alternative to competitors (diagrid, hexagrid, random Voronoi). Diagrids and hexagrids still remain more efficient in terms of forces and displacements but are characterized by a more usual appearance, instead Vorogrid offers more design control and better performances on average with respect to random Voronoi structures. This method is streamed into a pipeline that includes grid initialization strategies, geometric and structural optimization to mitigate the effects of the grid randomness, and structural sizing.
