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.
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.
Performance of diﬀerent optimization concepts for reactive ﬂow systems based on combined CFD and response surface methods
Optimization of reactive flow systems, e.g. coal and biomass combustion, gasification or partial oxidation, is usually a multi-parameter problem, while geometry configurations (e.g. reactor dimensions, burner dimensions) and operating conditions (e.g. fuel mass flow, reactor temperature, cooling capability) mainly determine the process efficiency and profitability.
Optimization of a conveyor transfer chute including particle flows
A common problem in the transfer chute is the unbalanced mass flow at the outlet conveyor. The objective consists in reducing the difference in curve averages of total mass in left and right part of the conveyor. Coupling Rocky DEM with modeFRONTIER enabled engineers to select the optimum design that reduced this difference to 0.2%.
INVERSE DERIVATION OF CONSTANTS FOR THE CONSTITUTIVE EQUATION AND FATIGUE MODEL OF PB-FREE SOLDER JOINTS BASED ON EXPERIMENT RESULTS, FINITE ELEMENT SIMULATION AND VIRTUAL OPTIMIZATION METHODOLOGY
A novel approach of deriving the constants for lead free solder creep constitutive equation and fatigue model has been proposed in this paper. In this approach, the constitutive parameters and fatigue model constants were determined retrospectively based on the test results of selected lead-free BGA packages, multi-objective optimization, and finite element modeling. ANSYS and modeFRONTIER are coupled in this methodology.
ESTECO webinar recording | A CAD-Mesh mixed approach to enhance shape optimization capabilities
In this joint webinar, ESTECO and RBF Morph present an innovative CAD-Mesh mixed approach to enhance shape optimization capabilities. Riccardo Cenni from SACMI describes how engineers at SACMI Ceramic Engineering Department leveraged modeFRONTIER, RBF Morph and ANSYS Workbench to develop an hybrid methodology combining CAD and mesh based approach overtaking the limits of the shape optimization based on the single disciplines.
Modelling and Multi-objective Optimisation of the VHP Pouch Packaging Sterilisation Process
This paper aims to optimize the pouch packaging sterilization process used in aseptic technology. The study is made of two parts: first the modeling and fluid dynamics simulation of the sterilization process on the pouch with a subsequent experimental validation, and then the multiobjective process optimization, with the aim of finding
the most suitable system configuration using modeFRONTIER.
Optimization of a single stage double suction centrifugal pump
In this study, the optimization of a double-suction centrifugal pump is developed and run with the objective being the maximization of its hydraulic efficiency. The optimization of the pump is performed by means of the modeFRONTIER optimization platform using MOGA II and ANSYS CFX software was used for CFD simulations.
Fluid dynamics Optimization of racing engine inlet ducts at Aprilia Racing
A two-step optimization procedure of intake valves and intake ports of the Aprilia RS-GP motorbike is presented in this work. Parametric geometry design, automatic mesh generation and three-dimensional CFD analysis are coupled with different optimization techniques – using the platform modeFRONTIER. The objective is the improvement of fluid dynamic efficiency of valve and port while simultaneously guaranteeing their feasibility.
