An Automated Head Impact Process Setup for Automobile Instrument Panel (IP) Application

FMVSS 201 procedure originally rolled out in 1968 by Federal Motor Vehicle Safety Administration to protect the automobile occupants from fatal injury during the crash. Since the beginning of the law, the automobile interior safety has become considerably more challenging for manufacturer to meet FMVSS 201 standard criteria. During the course of instrument panels (IP) development, engineers are heavily relied on computer simulation to optimize the design for a more robust design. Based on FMVSS 201, there are an infinite number of target points on the instrument panels that must be tested for head impact performance. Therefore, this becomes not only costly but it is impossible for the manufacturer to test all possible target points using the current conventional process.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments

The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

Optimizing Cooling Passages in Turbine Blades

Turbine blades have internal passages that provide cooling during operation in a high temperature engine. The design of the cooling passages is critical to achieve near uniform temperature of the blade during operation. The temperature of the blade is dependent on the thermal properties of the blade material as well as the fluid dynamics of the air circulating in the cooling passages. Computational optimization methods have successfully been applied to design lighter and more efficient structures for many aerospace structures. An extension of these techniques is now applied to guiding the thermal design of a turbine blade by designing the optimal cooling passage layout. Optimization methods will be applied to determine the optimum pattern of the cooling passages and then to optimize the size of the individual cooling passages. The goal is to produce a more thermally efficient turbine blade design that will produce blades with longer lives and better performance.

Altair's Model Verification Director (MVD) allows engineering analysts to validate CAD model data received from the design teams, automatically identifying potential issues that could slow down the pre-processing stage of the simulation life cycle. The MVD is embedded into HyperWorks pre-processing technology, HyperMesh and integrated into the Assembly Browser. The solution identifies CAD intersections, missing welds, and incorrect bolt-nut positions on an entire assembly structure and generates comprehensive reports in both Microsoft PowerPoint and Excel formats to allow for easy communication of the validation results. With this insight, the CAD design team can correct the model data and help streamline the finite element modeling process.

Altair BUSolutions

<b>Developing the World’s First Series Hydraulic Hybrid Bus</b><br><br> The Federal Transit Administration (FTA) requires modern transit bus systems to provide more efficient services across America. Currently, U.S. public bus transit authorities are subsidized to meet operating budgets with State and local subsidies exceeding $19 billion per year and Federal subsidies exceed $7 billion per year. The goal of the BUSolutions project is to design and manufacturer a new bus with improved fuel economy, lower emissions and a lower life cycle cost than today’s buses.

Virtual Durability Process: Bringing Together MBD, FE and Fatigue

Simulation is indispensable within any product development organization. We at Altair believe this outright and you see that in the vision statement from our CEO, to radically change the way organizations design products and make decisions. Simulation driven design is applied at different stages of development, from concept stage to the final design tuning and validation. Optimization is an integral part of it, so your starting point is an optimal design.

CAE Process & Data Management Using Altair Hyperworks Solution

Computer-aided engineering plays a significant role in the product development process. However, with the growth in the number of simulations performed, and in the absence of process and data management tools to track these simulations, inefficiencies start creeping into the CAE process. Altair Data Manager (ADM) is a pioneer tool in addressing this need. With this insight, the CAE group at Eicher Motors Ltd. decided to implement the ADM tool before process management and data migration became a Herculean task. Eicher CAE users wanted the ADM system to help them manage the complete CAE process and improve CADCAE integration. That included automated assembly buildup of batch-meshed components; automated part library buildup; analysis iterations management; faster and consistent report extraction; centralized data storage without any data duplication; and efficient sharing of results and reports across the organization.
