Optimization of engineering structures where multiple (more or less conflicting) objectives are simulta- neously considered, is getting more and more attractive in automotive industries. They usually involve a large number of design ...

During the fabrication of products, important material and process parameters, geometry and also external influences (e.g. room temperature) can vary considerably. It is known that they can have a substantial, even critical influence ...

This paper deals with the design and optimization of a vehicle bumper subsystem, which is a key scenario for vehicle component design. More than ever before, the automotive industry operates inhighly competitive environment. ...

The use of multi-disciplinary optimisation methods (MDO) in the development process of complex automotive structures is often hindered by several problems. The required resources for very expensive simulations such as crash or 3D CFD ...

Experimental quasi-static and dynamic tests were conducted over different types of advanced material samples, such as composite sandwich, in order to derive both mechanical and numerical input parameters for LS-DYNA material models. ...

Optimization and the improvement of robustness and reliability in the early stages of the product development is often attempted today using simulation methods together with algorithms that run these simulations in an automated ...

Structural analysis under consideration of the uncertainty of input parameters, such as loads, material, and geometry leads to uncertain time-dependent results. Such uncertain structural process shows for the uncertain input ...

With the ever increasing demand for the efficient use of materials to reduce manufacturing costs and product mass; the use of optimisation techniques have become common place in CAE. The optimisation techniques used for optimising in ...

The increasing demand to evaluate vast amounts of different load cases has led to a highly standardized and automated way of model assembling at AUDI. This model assembling is greatly assisted by the software “CAx Load Case Composer” ...

Topology optimization is a very powerful tool to develop new concepts and has been widely used in engineering problems involving static loading conditions. However, there has been relatively little work for topology optimization of ...
