Safety Comes First – Development of a Maxi-Cosi Child Seat Using a CAE-Driven Design Process

When developing a new child seat, safety is paramount. Dorel Juvenile, market leader in child safety in cars, was confronted with the task to develop a new child seat - the Maxi-Cosi 2wayPearl. To investigate and analyze the best feasible design, considering the occurring forces during an accident, Dorel Juvenile turned to Code Product Solutions, an engineering service provider that supports their customers in the development and optimization of products, using computer-aided engineering (CAE) tools. Within the development process, Code Product Solutions engineers employed the Altair HyperWorks CAE suite utilizing RADIOSS® for crash simulation, OptiStruct® for the layout of highly loaded plastic parts that comprise the reclining system, HyperMesh® for pre-processing tasks, and HyperCrash® and HyperView® during post-processing.

FIAT Customer Story

FIAT chose Altair ProductDesign as a partner to perform a pilot project to investigate squeak and rattle. The project focused on studying issues on the FIAT UNO, a vehicle made exclusively for the South American market. Altair ProductDesign suggested that FIAT implement Altair’s ‘Squeak and Rattle Director’ (SNRD), a comprehensive set of services and software automations that rapidly identify and analyze design alternatives to eliminate the root causes of squeak and rattle in assemblies. With customization from the Altair ProductDesign team, the solution provides a semi-automated approach to determine relative component displacements in the time domain that can lead to undesired noise. A dedicated four day workshop facilitated a fast ramp-up of the NVH team’s knowledge of the SNRD and helped Altair to identify FIAT’s specific design process that the solution could be tailored to.

Structural Component Design Optimization for Additive Manufacture

Additive manufacturing (AM) technology enables the possibility of realizing highly efficient, optimized structural components with configurations not achievable using conventional manufacturing methods. The Altair and Solid Thinking toolsets provide advanced capabilities to design structural topologies to minimize weight and maximize other performance criteria. However, conventional manufacturing processes require application of design constraints, such as directional access for machining, in the optimization that limit the structural efficiency of the resulting design. AM can remove many of these constraints to allow for more efficient configurations under the applied loading conditions. Case studies show the potential to reduce weight up to 30% for components with applied bending and torsional loads by allowing increased complexity configurations that could only be manufactured additively.

Teaching Aerospace Design Optimization

Engineers develop design and analysis skills through application of principles, methods, and tools to the solution of complex, often ill-defined problems. Engineering training that focuses on simple, focused component-level applications teaches some portion of the skills needed to execute real world problems but is incomplete. Altair has experience both deep and broad in applying optimization technologies and has developed a training curriculum aiming to teach engineers more comprehensive design optimization skills and knowledge in aerospace applications. The Altair Aerospace Optimization Academy has been developed as a series of online modules to develop deep design and optimization knowledge and skills in engineers that have basic structural analysis and finite element experience. The training curriculum leads students through complete design cycles using Altair’s advanced optimization technologies and explores the different approaches that engineers can use to develop aerospace designs for a variety of metallic and composite components and configurations.

Lead Time Reduction using Automatic Reporting Director (ARD) for MAHLE

Mahle is one of the top automotive suppliers and one of the top 3 piston suppliers worldwide. With the recent advancements in numerical simulation and computing power, the FEA process has become a major tool to look at the reliability of different design variants. With these advancements, the reporting aspect remained a relatively unchanged process of manually creating pictures and tables with all of the different results. This presentation will look at the collaboration work between Mahle and the Altair Product Development (PD) team to customize the Automatic Reporting Director (ARD) for Mahle's requirements. The goal was to use to better utilize the engineers time by automatically generating a report with standard formats, pictures, and tables. By using the ARD tool, Mahle was able to reduce the lead time for a report from over 4 hours down to less than 1 hour.

Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance

The automotive industry, in its constant quest for weight reduction, is increasingly considering composite materials as a substitute for sheet metal components to meet future fuel consumption standards. However, composite forming processes are expensive and difficult to control because of the complexity of the material behavior with fiber and matrix layers or plies and its dependency on many parameters, such as non-linearity of tensile stiffness, effect of shear rate, temperature and friction. Hence, numerical simulation could be a viable approach to predict material behavior during composite forming. The objective of this study is to highlight capabilities of RADIOSS™ to simulate forming simulation of composite plies made from woven fibers, each ply modeled as a layer of woven fibers along two directions of anisotropy, warp and weft. For validation the well-known double dome model published in NUMISHEET’05 proceedings is used. The compared result is the shear angle after stamping that is, the final angle between warp and weft fibers, at several prescribed points on the ply. The variation of this angle has a strong impact on material characteristics which severely deteriorates when a critical value is reached. Hence, a study on crash simulations is performed, after mapping fibers angles from stamping simulation.

Meshing the Human Lumbar Spine

HyperWorks customer Jeff Harris from NuVasive has used HyperMesh to solid hybrid mesh consecutive human vertebrae and discs from a patient bone scan. The meshing, set up in Hypermesh, is simulated using Ansys for motion limits, stiffness, and disc material correlation. Once a model is correlated, disc implants are modeled and simulated with the goal of replacing degenerate discs.

Advances in EM Simulations

This paper introduces some of the recent extensions to the computational electromagnetics code FEKO as released in Suite 7.0. The FDTD (Finite Difference Time Domain) method was added to the selection of available solvers. MLFMM (Multilevel Fast Multipole Method) and PO (Physical Optics) were hybridized for electrically large applications. The RL-GO (Ray-Launching Geometrical Optics) solver was extended and improved in terms of speed and accuracy, and a new interface to import measured near-field antenna data from MVG/Starlab will be presented.
