Advanced numerical optimization methods in the rapid product development process of diesel engines
BMW leveraged modeFRONTIER to optimize the fatigue life of a diesel engine crankcase and gasket. The objectives were to maximize safety factors at the inter-cylinder walls, while maximizing the minimum bead pressure during the low temperature phases of combustion.
Investigation and Customisation of Snowboard Performance Characteristics for Different Riding Styles
The major aim of the research is to fully characterise the design of modern snowboards in terms of feel through identification and customisation of their on-snow performance characteristics. The software package Esteco modeFRONTIER is employed to determine the optimal design solutions, where the performance targets are derived from the expert rider survey/interview/test process.
Optimization of a Boomerang shape using modeFRONTIER
Achieving best performances for a product need first of all to define the metrics of the performances and design options. Once these are clear modeRONTIER can drive the simulation software to high end result. A boomerang is a flying object quite simple in shape but challenging in the physics...
Bombardier uses modeFRONTIER to optimize high-speed trains
Bombardier uses modeFRONTIER to optimize high-speed trains for drag reduction and improvement of cross-wind stability. In recent years, the German and Swedish based company has turned to modeFRONTIER to drive the design simulations, in order to try to achieve improved greater drag reduction, increased speed with lower traction power and increased cross wind stability.
Automotive Aerodynamic Design Exploration Employing New Optimization Methodology Based on CFD
In the past few decades, a number of environmentally friendly technologies in the automotive industry have been developed. Automotive styling is also regarded as an important factor in resolving environmental issues by reducing drag force, which results in high fuel efficiency. This paper demonstrates an efficient automotive aerodynamic optimization process and automatic system based on CFD.
Automatic calibration of internal combustion engine parameters 3-axis
The main purpose of the collaboration between Alma Automotive and ESTECO is the implementation of a demonstrator able to highlight the added-value given by coupling National Instruments devices with modeFRONTIER framework, while exploiting specific applications developed by Alma Automotive for the engine set-up.
CFD optimization for GDI spray model tuning and enhancement of engine performance
Coupling a 3D Computational Fluid Dynamics (CFD) tool with a rigorous method of decision making is becoming indispensable in the design process of complex systems, as internal combustion engines. CFD based optimization (CFD-O) is here carried out on a single cylinder, four-valve, four-stroke gasoline direct injection (GDI) engine, to enhance mixture formation under stratified charge operation, hence to choose between the single or double injection strategy maximizing the engine power output.
Fatigue Assessment of Panaro Bridge
In this paper, preliminary studies performed on the Italian case study, the Panaro Bridge, are reported. In particular, results of the standard fatigue assessment according to Eurocode rules were compared with the actual fatigue damages occurred to deck secondary components to obtain a preliminary critical review of adopted fatigue assessment methodologies.
Strength Improvement to Composite T-Joints under Bending through Bio-inspired Design
This paper shows that a bio-inspired design methodology is an effective method to strengthen composite T-joints under bending loading, whose ply angles were tailored using an optimisation program mimicking the evolutionary process of adaptive growth.
Prestress optimization of hybrid tensile structures
This paper deals with cable domes design and study the role of the cable prestress and of the prestress optimization. In particular it is shown how, for a generic spatial truss, a suitable cable pretensioning makes us able to assign a geometrical stiffness to the whole structure and, in this way, to improve its overall behavior.
