iChrome’s software solutions, Nexus and Shaper, have been instrumental to Same Deutz-Fahr, a leading tractor manufacturer, to achieve weight reductions and an overall performance increase of complex 3D assemblies such as Front Axle Supports. The main objective of this work was to improve the initial shape of a tractor front axle support with the goal to minimize the overall weight under performance requirement constraints. An overall weight saving of 15% compared to the previously adopted design, has been ...Continue Reading →
This work combines Moving Least Square mesh morphing methods with classical optimization techniques to optimize Composite Stiffened Structures against buckling constraints. The idea is to use standard optimization methods to handle thicknesses and percentages of the composite laminates and Moving Least Square morphing capabilities to modify the shape of the stringers without generating new meshes from geometry during the optimization process.
The considered structural assembly is reported in the figure below. A flat panel with ...Continue Reading →
Organic Rankine Cycle (ORC) turbogenerators usually operate in thermodynamic regions characterized by high pressure ratios and strong real-gas effects in the flow expansion, requiring therefore a non-standard turbomachinery design. An effective approach can be based on the intensive use of Computational Fluid Dynamics (CFD) and optimization procedures to investigate a wide range of possible configurations.
Expansions through impulse stages of ORC turbines are commonly characterized by large pressure ratios and a low speed of sound ...Continue Reading →
Aerodynamic efficiency is a key aspect in commercial aircraft design as it allows reducing fuel consumption and meeting emission and performance requirements. The main goal of this work is to improve the initial shape of the wing of an innovative three lifting surfaces configuration aircraft in order to minimize drag at transonic cruise condition.
The classic approach to aerodynamic shape optimization requires the definition of a geometrical parameterization of the CAD model. In this case, ...Continue Reading →
The challenge is to perform a feasibility study aiming at replacing the single-sided swing-arm for high performance MV Agusta F4 1000R and “Brutale” 990R/1090RR motorcycles made in aluminum alloy with a Resin Transfer Molding (RTM) carbon composite one. Injection-based technologies for long fiber reinforcement, such as RTM, have been found particularly rewarding for motorsport cars and motorbikes.
After an initial re-assessment of shape and design of the part to make it more suitable to be ...Continue Reading →
