Designing Lighter Products with modeFRONTIER

The increasing demand for lightweight products brings challenges for designers in all industrial sectors, especially those in the consumer goods, aerospace and automotive fields.

Lighter products play a crucial role in reducing the impact of industry on the environment by cutting down the use of raw materials in the production phase and reducing fuel consumption and carbon emissions.

Optimization and Integration for Lightweight Design

Lightweighting can be achieved either by using new generation materials, as opposed to heavy traditional structures, or by reducing the mass of components as much as possible. In both cases, weight targets need to be offset against other design standards to avoid the risk of compromising the overall performance and safety of the product.

Considering these issues in the early stages of the design process and integrating all problem dimensions using a multidisciplinary and multiobjective approach, lightweighting becomes crucial to avoiding product failure and for reducing environmental impact through lightweighting.

modeFRONTIER Lightweight Applications

In any method adopted to achieve a lighter design, modeFRONTIER’s integration capabilities with the most commonly used CAD and CAE tools have proven essential to engineers by:

  • automating the exploration of the design space in the search for a best compromise between weight and performance
  • streamlining shape optimization by automatically adjusting geometry parameters to, and counterbalancing weight with, structural compliance standards
  • integrating data from CAD tools, multibody analysis and simulation solvers for structural simulation into a seamless workflow

Optimization can be performed at the molecular modeling level or the composite properties level and can even be simulated when coupling modeFRONTIER with dedicated software solutions like eXstream Digimat, ANSYS Composite PrepPost (ACP) or tools capable of simulating real world dynamics like LS-DYNA.

No matter the objective, modeFRONTIER’s optimization methodologies can integrate multiple data streams into one seamless, multiobjective strategy for lightweight designs.

 

A few examples

This paper describes how the optimum weight and the angle of attack of a Formula 1 front wing were determined through a two-step optimization approach including ANSA BetaCAE and NASTRAN’s SOL 200 Topometry Optimization tools and a genetic algorithm within modeFRONTIER.

Targeting multiple objectives such as lowering aircraft drag, wing weight, and the environmental impact of lower speed conditions (i.e. take-off and landing) enhances the overall environmental performance of fuel consumption and noise generation. In this paper, modeFRONTIER aided the Italian leader of complex aeronautical systems to enhance aerodynamic performance by 2.5% and reduce wing weight by 4%.

See how illy achieved the perfect espresso in this paper. illy produces its Iperespresso capsules with specific geometric and mechanical properties. Faced with the task of reducing the amount of plastic used and cutting CO2 emissions, illy engineers were required to redesign capsule geometry while adhering to strict physical constraints.
