Handling the Complexity of Mechatronic System Design
Two design projects highlight how ABB Group leverages optimization-based development to handle the complexity that automation and control systems entail and to maximize mechatronic product performance, meet reliability demands and ease overall environmental impact.
Application of Optimization Methodology and Specimen Speciﬁc Finite Element Models for Investigating Material Properties of Rat Skull
This study represents a preliminary effort in the development and validation of FE models for the rat skull used to predict the reaction of traumatic brain injuries (TBI) in humans. modeFRONTIER automatically updated input parameters and submitted new keyword files to LS-DYNA, which ran in MPP mode, to reduce the time needed in completely the task. This same method can be used to other reverse engineering procedures to obtain accurate material parameters for FE models development.
The best compromise between stress and weight at SACMI
SACMI is a global OEM (Original-Equipment- Manufacturer), market leader in the production of machines and complete plants for the Ceramics, Packaging (Beverage and Closures&Containers), Food and Plastics industries. The goal of this analysis was to find a light but strong piston geometry in order to improve the Compression Molding Machine performance in terms of tensile and yield strength.
Optimization of engine torque using variable valve actuation systems
The aim of the work is the maximization of engine torque optimizing the Variable Valve Actuation Systems parameters: intake valve timing, exhaust valve timing and intake valve lift and opening duration. The VVA system is not present in the studied 3.2L, V6, GDI engine with double VVT (intake and exhaust). In the design phase, engine performance variation is studied to understand if the adding the VVA system could enhance torque.
Upfront CAE Driven Design “The Future of Simulation”
Competition and customer demand are constantly pushing automotive manufacturers to launch new models at shorter intervals while satisfying the ever increasing demands in performance, environmental impact and costs. In order to remain competitive, an automotive OEM must cope by applying continuous pressure to reduce cost and improve design while reducing deployment time.
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.
