Mabe

The consumer goods industry is fast paced and highly competitive, with designs becoming increasingly complex while the timeline for production shrinks. Companies like Mabe must innovate and develop new products quickly in order to remain on the consumer radar, and conducting various analysis studies on their designs helps them to do so. This project addresses the tedious and time consuming task of modeling the foam within the product door that helps maintain the internal temperature and also absorbs shock in a drop situation. Modeling the foam effectively is complex and difficult due to the complicated nature of the doors and other cavities, so the step was often skipped, causing inefficiencies with the product.

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.

F.tech R&D North America

F.tech R&D North America utilizes HyperView to investigate test results, using the data to inform decisions on methods to improve designs. This data will often be used to create reports and presentations during the development process, using images and animations generated by HyperView to illustrate particular areas of a component where additional work may be required. However, exporting these assets is a highly manual process of loading in results, positioning the model and taking screenshots. To allow its engineers to concentrate efforts on exploring and interpreting the results, F.tech R&D North America wanted a way of automating this process.

Model Verification Director

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.

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.

Mahle Discuss Its Use Of The Automated Reporting Director

A close collaboration was forged between MAHLE and Altair ProductDesign to create the automated reporting solution. While Altair ProductDesign developed the code, MAHLE described the current process and reporting requirements to ensure business alignment and an effective result. Previously, users had to create a HyperView session, adjust all the pictures, snap a picture of each desired view, bring the visual assets into PowerPoint, crop and place, go back and create call-outs, and re-examine results to create notes for the report; this is now a push button operation. Using ARD, MAHLE has successfully reduced time spent on non-engineering tasks, enabling CAE analysts to better utilize their time as engineers - yielding more analysis and better design.

Daimler - Calculation of Optimal Damping Placement in a Vehicle Interior

One of the most difficult jobs of a NVH Analyst is to sift through a seemingly endless set of results and find the key conclusions that will improve a design. Different assumptions and different subsets of data can give very different conclusions.

A hybrid finite element formulation for a beam-plate system

Appropriate damping elements are introduced in the connections between stiff and flexible members in order to capture the presence of the flexible members during the analyses of the stiff ones. The component mode synthesis method is combined with analytical solutions for determining the driving point conductance at joints between stiff and flexible members and for defining the properties of the damping elements which represent the flexible members when analyzing the stiff components. Once the vibration of the stiff members and the amount of power dissipated at the damping elements has been identified, an EFEA analysis is performed in order to determine the amount of vibrational energy in the flexible members.
