Steady state cam optimization process for optimal engine operation over the speed-load map
A gasoline engine is an energy conversion device, where chemical energy is converted into mechanical energy. Many technologies aim to decrease the net indicated fuel consumption (eg. downsizing, Atkinson/Miller cycles, lean/dilute operation, optimal design, etc.). By optimizing cam timing over a speed-load map, subject to constraints, further efficiency improvements can be gained.
Optimization of Suspension Design for Commuter Motorbikes
Suspension design variables plays a key role when adapting a motorbike to different road a traffic condition. Steering torque and ratio rate should be considered for different type of maneuvre, along with acceleration at rider center of gravity when coming to comfort parameters.
Optimization of a Turbo Charger Compressor at BorgWarner using AxCent and modeFRONTIER
This work presents a numerically optimized design approach to turbo charger radial compressor development for commercial diesel applications. The design optimization includes both aerodynamic and structural components, combined via a “loosely coupled” iterative procedure. The primary goal of the design is to maximize total to static efficiency at various operating conditions, while also preserving or expanding the overall operating range of the compressor, and doing so with a structurally sound geometry.
A New Automated Underhood Thermal Management CFD DoE Workflow with ModeFRONTIER
Ford engineers are challenged to find a cost efficient cooling system concept for the underhood thermal management that suits different powertrains and environments, respecting standards (NACA duct) and without compromising the vehicle’s aerodynamic performance. From a thermodynamics perspective, the problem to address regards the high temperatures deriving from the friction inside the PTU (Power Take-off Unit) and surrounding parts which can cause the oil to overheat.
Improved System Design of an Emergency Department through Simulation-Based Multi-Objective Optimization
A University of Skövde researcher studied the organization of the Emergency Department (ED) of the Hospital of Skövde on how to best meet the requirements established by the County Council concerning waiting-time for triage, physician examination and total lead time though the system.
Multi Objective Optimization of Medium Voltage Reclosers
Medium voltage reclosers are protection devices for medium voltage grid operators which are often integrated into overhead line towers. Finding the right configuration for the components piloting the process is not only crucial in terms of recloser lifetime but also enables excellent switching properties, ultimately improving energy performance.
