Multi-objective Optimization of A-Class Catamaran Foils Adopting a Geometric Parameterization Based on RBF Mesh Morphing
The design of sailing boats appendages requires taking in consideration a large amount of design variables and diverse sailing conditions. The operative conditions of dagger boards depend on the equilibrium of the forces and moments acting on the system. This equilibrium has to be considered when designing modern fast foiling catamarans, where the appendages accomplish both the tasks of lifting up the boat and to make possible the upwind sailing by balancing the sail side force. In this scenario, the foil performing in all conditions has to be defined as a trade-off among contrasting needs.
Multiobjective sizing optimization of seismic isolated reinforced concrete structures
A well-designed base isolation system can largely reduce seismic loadings transferred to the superstructure and it not only enables to immediately reduce the superstructure building cost, but also to reduce the maintenance costs incurred after every earthquake during the building lifetime. To better understand these factors, this paper presents an efficient numerical optimization technique for comparing the responses of a base-isolated and a traditional fixed-base reinforced concrete ordinary building under the same type of solicitations and seismic spectra, as appropriate for each case.
Design and simulation of additive manufactured structures of three component composite material
Lattice structures have become widespread in many areas. Their obvious advantage is the light weight and significant cost savings of a material. Application of unidirectional composite materials allows preserve the exceptional strength properties of composites in construction regardless of the loading direction. For this reason, the lattice composite structures are actively used in the aerospace industry. The goal of this work is the study of the property change of lattice structures of three component composite materials depending on their parameters, as well as the determination of optimal configurations of these structures.
Energy and daylighting optimization for an office with fixed and movable shading devices
In this paper, external fixed shading device geometry is optimized in order to reduce the overall energy consumption in an office room provided with an extensive glazing and moveable Venetian blinds. The optimizer modeFRONTIER drives the optimization using DAYSIM for internal illuminance and lighting electrical loads computation and ESP-r for building energy simulation. Here both the FAST and NSGA II genetic algorithms have been applied using the simplified approach of DAYSIM.
Parametric Optimization of a Ladder Vehicle Chassis
In this optimization process, modeling and simulation are done by coupling softwares ANSYS and modeFRONTIER. The objective is the reduction of dimensions of a vehicle ladder chassis, using a Cargo C-816 model, conceptually compound by two stringers and five traverse beams that connect them. FEA and concepts of manufacturing processes and mechanic of materials are used to certify the structure’s integrity after the initial volume reduction.
