Altair Product Design Aircraft Interiors
While much attention is paid to the “look and feel” of an aircraft interior, the main purpose is to provide convenience and safety to the passenger. The overhead bins should be easy to access and close securely, seats should operate efficiently while keeping the passenger secure, and the doors and exits should perform their function in all conditions. Altair Engineering’s technology coupled with Altair ProductDesign expertise has helped many companies improve the performance, reduce the weight, and increase the safety of aircraft interior systems.

Altair Product Design Automotive Weight Management
Too often weight is improved undesirably as a post-launch development initiative or realized through performance degradation late in the program cycle. The Altair ProductDesign process considers weight as a primary attribute from program inception, tracked throughout the design phases. By considering weight in multi-attribute optimizations, mass targets are met. Attribute performance screening, early global structural studies and local component optimizations are a few of the techniques that are employed.

Bombardier Transportation - Fast Tracking Rail Vehicle Design
Bombardier Transportation UK offers one of the most comprehensive and diverse rail vehicle portfolios in the world. The strategy is one of continuous development that provides the most effective and cost-efficient rail solutions for today and the future. A key ingredient is the use of Altair HyperWorks enterprise computer aided engineering (CAE) solution. Altair's technology is now present at every stage of the design process and has increased the efficiency of the product development process. The paper details how Altair tools have been used to generate Finite Element (FE) models of carbodies, bogies and secondary structures in reduced time scales. Significant weight and cost savings are achieved through structural optimisation of components such as large steel castings, aluminium extrusions and steel fabricated structures which are subjected to linear static, fatigue and abuse loading. Automated post processing facilitates the interpretation of results and the writing of detailed official reports.

Groupe Finot
Achieving a 100kg Weight Saving
The Fila features a hydraulic “canting” keel which plays a crucial role in sailboat racing. Its job is to re-right the boat when the wind tips the boat to one side – or even capsizes. When the boat lists to one side, there is more wetted surface area and friction as the boat cuts through the water, resulting in reduced speed. The canting keel, which rotates around the boat, increases the stability and speed of the boat by keeping it upright with the sails in the wind. The goal of the Altair ProductDesign team was to optimize the internal structure of the keel to reduce weight, lowering its center of gravity and attain maximum rigidity.

Heart Valve Analysis
Predicting Aortic Stenosis through Simulation
Aortic valve Stenosis is a heart value disorder that narrows the aortic valve opening due to calcium build up in the leaflets. This prevents the valve from opening properly and obstructs the flow of blood causing the heart to work harder. Finite Element Analysis (FEA) has the potential to allow researchers to study the condition without the need for traditional physical testing. An efficient process was required to make this possible since modeling tissue behavior, back pressure, and the interaction between tissue and blood are highly complex challenges. Altair ProductDesign led this self funded project to improve the simulation and analysis of heart condition research.

Lightweight SUV Frame Design Development
The Lightweight SUV Frame project is a research initiative of the Department of Energy and the Auto/Steel Partnership (A/SP), designed and engineered by Altair Engineering, Troy, Mich., with the key objective to reduce the baseline frame structure’s mass by 25%. This Phase I study focused mainly on frame system performance and mass reduction. Cost considerations were not a driving factor for this Phase I design effort, however cost was monitored throughout. Analyses and advanced techniques for applying material, architecture and design were used to develop a non-traditional lightweight frame (Figure A). This new frame is 23% lighter than the baseline frame, while maintaining the baseline structural performance.

Reducing Vessel Weight & Operating Costs
Liquid sloshing limits the carriage of LNG in large side to side membrane tanks to be either over 80% or less than 10% full to avoid damage to the tank lining and insulation. The Cubic Donut Tank System (CDT) was first patented by Prof. Thomas Lamb (Prof. Emeritus, Univ. of Mich.) in 1976 and is less expensive to construct than spherical and membrane LNG tanks. Altair ProductDesign recognized the merits of the invention but noted that the patent in is original form faced several structural issues in regard to hydrostatic and sloshing loads.

Thermal Management with Altair Product Design support: Ceramic simplifies Heat Dissipation within LEDs
LEDs suffer heat problems limiting their success as a light source. To improve the heat characteristics of LEDs much attention is given to the heatsink, less to the layers and barriers between LED and the heat dissipating surface. A change of concept and material, as carried out in a consulting project by Product Design, an Altair business unit, for CermTec AG shows how significant gains in thermal management and reliability as well as a simplified system can be reached. As shown in the consulting project, using ceramics as heatsink, circuit carrier and part of the product design opens the chance to overcome traditional patterns. A simulation process based on Computational Fluid Dynamics supports thermal optimization and technical product design. Within the following case study we will show how the new theoretical approach works, validate the concept and describe how improvements
with ceramic heatsinks can be achieved.

Weight Optimization of Turbine Blades
Optimization of aircraft structures and engines for minimum weight has become important in the recent designs. Topology optimization of airframe structures, wings, and fuselage … is now practiced since last 3-4 years to reduce weight considerably in ribbed members, rotating structures in engines is of much more recent origin. Designers have been practicing to remove some material in the blade platform area by analysis. This weight removal can be optimized to obtain maximum reduction without compromising the structural integrity. This procedure is illustrated in this paper by using two optimization codes, Altair OptiStruct for linear structures and Altair HyperStudy for nonlinear structures using Ansys platform as the main solver. Using this procedure nearly 10% weight reduction is achieved.
