Driving Million Dollar Savings at Ford using Structural Optimisation
The automotive business is a very competitive industry and in today’s markets, leading manufacturers are keen to find ways of reducing costs without compromising either quality or performance. This paper will cover the process of applying OptiStruct software to the re-development of a high volume and high cost plastic PAS (Power Assisted Steering) pump bracket into a much cheaper aluminium alternative. The outcome of this was a lighter, stiffer and cheaper replacement bracket that had the potential, based on the current production engine volumes, to save Ford Motor Company over $1.1 million a year.

Topology Optimization of Aircraft Wing Box Ribs
This paper considers the application of conventional energy based topology optimization methods for design of aircraft wing box ribs. Compared to standard topology optimization work undertaken at Airbus, the topology optimization of wing box ribs posed several additional challenges, mainly due to the wing box ribs being embedded in a redundant wing box structure. Several approaches to solving this problem have been investigated and are being reported as part of this paper, including a global analysis/optimization approach and two local analysis/optimization approaches.

Optimisation Techniques Leading the Development of a Steering Wheel
The early application of structural optimisation in the design of automotive components streamlines the design process and at the same time significantly increases the potential of the final design achieving maximum performance. This paper details the use of optimisation techniques during the development of a steering wheel, to generate an optimised design for cross attribute performance. This was completed in the Altair HyperWorks environment as Altair HyperMesh combined with Altair OptiStruct enables the creation of a parametric model with a multitude of design variables (i.e. size, shape, displacement, stress and frequency) in order to satisfy NVH, manufacturability, durability and crash targets.

Programmable, Open-Architecture HyperWorks Helps Toshiba Design Smaller Hard Disk Drives to Meet Market Demand
Toshiba Digital Network Company, faced with increasing global competition in the hard disk drive (HDD) marketplace, set out to create an advantage through the redesign of their existing HDD product(s). To support this effort, Toshiba partnered with Altair Engineering to automate its design process. This was accomplished by leveraging HyperWorks powerful modeling, visualization and optimization software applications with Toshiba’s proprietary solver for fluid dynamics. The specific goal was to optimize the air bearing surface (ABS) of the HDD’s magnetic head slider. This unique product development process resulted in minimizing the flying height as much as possible while considering its stability. This, in turn, reduced the overall size of the HDD and increased its recording density. In addition, the new design was brought to market in significantly less time than with Toshiba’s traditional design process.

HyperWorks CFD Optimization Increases Catalytic Converter Life and Efficiency for Eberspächer
To increase the product life and efficiency of its industry-leading catalytic converter, global automotive supplier Eberspächer GmbH used Altair’s HyperMesh (the finite-element analysis [FEA] and computational fluid dynamics [CFD] pre-processor) and HyperStudy (the solver-neutral design study and optimization tool). Both are part of HyperWorks, the engineering framework for product design. Combining the morphing capabilities of HyperMesh with HyperStudy, Eberspächer redesigned the shape of its catalytic converter to increase the flow uniformity and decrease the pressure drop. The redesign, in turn, increased product life and efficiency.

Applications of OptiStruct Optimisation on Body in White Design
The application of topology and size and shape optimization for the design of efficient automotive components in terms of mass and stiffness has developed into a well practiced discipline. Subjecting a vehicle body structure to this type of development enables the analyst to optimise the size, shape and placement of load bearing members. By defining the most efficient topology, structural targets can be achieved with fewer design iterations, therefore, leading to reduced cycle times and lower development costs. The Altair OptiStruct software suite provides the analyst with an optimization environment which realises this method by providing a ‘right first time’ approach to body design.
This paper presents an insight into the development of an efficient body structure subjected to various load cases. Based upon the topology of the load paths, which OptiStruct defines, the paper then details the development of the concept through to a detailed design.

Topology Optimisation Used to Achieve Frequency Targets of an Engine Bracket
Topology optimisation technology is becoming increasingly used in the design process of automotive components. This technology can be applied very effectively to simultaneously achieve static compliance and frequency targets for structural designs. The paper provides an industry perspective on how this technology is applied to a production bracket and the important role the designer and engineer play in converting the optimised material layout into a component which can be manufactured. It is demonstrated that the combination of topology optimisation and design knowledge can provide a design solution which could not otherwise have been achieved.
