OPTIMHEX Project - developing an innovative methodology for Heat Exchangers (HE) design
Develop a versatile, innovative methodology for designing virtual HE models that targets performance, materials, weight, size and manufacturability as an alternative to conventional approaches requiring prototyping and physical testing.
Optimization Applied to the Bearing Design of an Automotive Subsystem
Researchers at SKF Automotive Development Centre aimed at improving their bearing design for automotive subsystems by reducing the friction at the wheel-end by 30% while respecting the life service requirements. The results of each study listed remarkable improvements (up to 19%) and allowed researchers to consider different bearing configurations, in terms of number of rollers and size, and spot the optimal friction reduction conveying robustness improvements to the bearing.
Applications of modeFRONTIER in Liquid Propellant Rocket Engine Design
The design of the L75 rocket engine, which started in 2008, required liquid oxygen/kerosene as propellant pair, 75 kN of thrust in vacuum and an estimated specific impulse of 324 s. However, in 2013 the engineers switched to ethanol as fuel, which caused a 30% power decrease calling for engine design re-definition.
Development and optimization of hydroxyapatite-ß-TCP functionally gradated biomaterial
In this work a method of optimization of mechanical behaviour of an FGM biomaterial coating or scaffold composed of HAP and beta-tricalcium phosphate (ß-TCP) is considered. For coating on titanium-based substrates which have anatase (TiO2) top layer, thermodynamic equilibrium was analysed and the “safe” compositional path was found to ensure preservation of original ceramic phases during processing.
Structural Optimization in Early Design Phase @ VOLVO Cars
The presentation examines the structural optimization done in early stages of the design phase.
Fluid-dynamic design optimization of hydraulic proportional directional valves
This article proposes an effective methodology for the ﬂuid-dynamic design optimization of the sliding spool of a hydraulic proportional directional valve: the goal is the minimization of the ﬂow force at a prescribed ﬂow rate, so as to reduce the required opening force while keeping the operation features unchanged. A full three-dimensional model of the ﬂow ﬁeld within the valve is employed to accurately predict the ﬂow force acting on the spool.
Towards Zero Energy Industrial Halls- Simulation and Optimization with Integrated Design Approach
Net-zero energy building (NZEB) is thought to be the building of choice, but in practice, is also synonym to high investment cost. It is, therefore, very important to investigate if the amount of the additional capital investment could be recouped from the energy saving (or generation).
Finite element reconstruction of real world aortic injury in near-side lateral automotive crashes with conceptual countermeasures
Traumatic rupture of the aorta (TRA) remains the second most common cause of death associated with motor vehicle crashes after brain injury. On an average, nearly 8,000 people die annually in the United States due to blunt injury to the aorta. It is observed that more than 80% of occupants who suffer an aortic injury die at the scene due to exsanguination into the chest. With the advent of more accurate and established human body finite element (FE) models, FE crash reconstruction methods may become a valuable tool when assessing crash scenarios and occupant injury mechanisms. The current study is divided into five main aims, near side left lateral real world finite element reconstructions, sensitivity study, thresholds for TRA, aorta mechanics in racing crashes and conceptual countermeasures. In the first study eight nearside left lateral impacts, in which a TRA occurred, were reconstructed using a combination of real world crash data reported in the Crash Injury Research and Engineering.
Vehicle Aerodynamic Shape Optimization
Recent advances in morphing, simulation, and optimization technologies have enabled analytically driven aerodynamic shape optimization to become a reality. This paper will discuss the integration of these technologies into a single process which enables the aerodynamicist to optimize vehicle shape as well as gain a much deeper understanding of the design space around a given exterior theme.
