AIRBUS - Targeting Composite Wing Performance – Optimum Location of Laminate Boundaries
This paper investigates the application of newly available optimization functionality available in OptiStruct to provide design guidance to generate innovative laminate composite solutions. Due to the flexibility of laminate composites, it has great potential to exhibit displacement characteristics that could significantly increase the aerodynamic performance. Free element sizing technology is used to determine concept lay-up solutions.

UNILEVER - Design Development of a New Consumer Personal Care Product Pack Driven by Optimization
A new deodorant pack development process is described, which introduces advanced simulation and optimization technology into the concept development phase. Detailed predictions of interacting parts in a mechanism assembly are made possible through use of advanced simulation technology. Design optimization is then employed using the modelling as a virtual testing ground for design variants. The approach provides clear design direction and helps to improve performance and reduce uncertainty in the development process.

MEDTRONIC - Step Change in Design: Exploring Sixty Stent Design Variations Over Night
This paper investigates how recent developments in Computer Aided Engineering (CAE) and computer hardware combine to facilitate the rapid exploration of many stent design variations. On an example baseline geometry considered the radial stiffness was significantly enhanced with an improvement in structural performance. This represents a step change in the CAE assessment of a stent design.

FORD MOTOR COMPANY - A New Approach to Optimizing the Clean Side Air Duct Using CFD Techniques
An integrated approach to CFD design optimization is proposed. It consists of taking an initial CAD design, meshing it using HyperMesh, analysing it using Star-CD, parameterising its key features using HyperMorph, and then shape optimizing it using HyperStudy. This approach has been applied here to the shape optimization of the compressor inlet duct of a turbo system.

JAGUAR & LAND ROVER - Simulation of Automotive Exhaust Noise Using Fluid Structure Interaction
The feasibility of modellinggas temperature using RADIOSS CFD, a commercial code with both FSI and CAA (Computational Acoustic Analysis) capability has been investigated in this paper. A single skin manifold was modelled with flow boundary conditions obtained from a 1D engine simulation code. Engine test bed measurement in a semi-anechoic cell were compared with the prediction, and good correlation achieved. The method adopted provides support at an early stage in the development process.

SIMPACT - UK Niche Vehicle Industry Joins the CAE Fast Lane
This paper describes how Kent-based niche sports car manufacturer, Caterham Cars used Simpact and the Altair CAE toolset to help them radically improve the crash safety of their Seven sports car. The RADIOSS non-linear solver within HyperWorks was used to develop a new safety steering system. The project successfully concluded with the new design being certified experimentally under ECE-R12 and approved by the VCA.

GRACO - A Holistic Virtual Design Process Applied to the Development of an Innovative Child Seat Concept
Graco has worked with Altair Engineering to develop a group 1 Child Restraint System (CRS) using an advanced CAE driven design process. The design process introduces a number of key phases in the design cycle each of which are positioned to maximize the efficiency of the structure and reduce or remove the cost involved in a traditional, iterative 'test it and see' approach.

McLAREN CARS - Simulating the Suspension Response of a High Performance Sports Car
This paper highlights the use of Altair HyperWorks to assess and then optimize the performance of a McLaren Automotive front suspension system. The tools MotionView and MotionSolve are used to build the model and then carry out initial assessments of kinematics and compliance characteristics. Altair HyperStudy is then used to optimize the position of the geometric hard points and compliant bush rates in order to meet desired suspension targets.
