HyperView Automation for Post-Processing Cell Phone Drop Simulations

The cell phone design cycle within Motorola has matured to the extent that it is standard operating procedure to analyze several concepts of a specific model before physical parts are ever made. With the use of HyperWorks tools and the speed of current compute systems, pre-processing and number-crunching are no longer the bottlenecks in analyzing full assemblies during drop situations. The most time-consuming part of the analysis cycle for drop simulations has become post-processing. It is common in the analysis cycle to look at the results of 10 or more drop orientations for each concept. Each cell phone assembly is large enough that it manually takes a half- to a full day — depending on the drop orientation — to look at all the parts of interest. By teaming with Altair, HyperView has been customized to automatically produce a web-based report for a drop orientation in about 45 minutes. The report can be accessed by any member of the design team and provides a much quicker method for focusing on the critical components that need attention.

Sheet Metal Transfer Simulation Using Altair HyperDieDynamics

The sheet metal part transfer process in high-volume transfer press is a critical phase of stamping manufacturing operations. Thus, understanding the dynamic behavior of sheet metal during transfer from die station to station becomes an urgent task in the tooling design phase. The goal is to achieve optimum transfer motion design, avoid high-cost equipment damage and improve production uptime. The newly developed Altair HyperDieDynamics is a unique tool to analyze sheet metal transfer dynamic behavior through its intuitive graphic user interface and engineering intelligence. By introducing the flexible body property and the virtual model of the stamping press line, users can easily conduct a panel transfer dynamic analysis with MotionSolve, and visualize the in-motion blank deflections, accelerations and resultant forces. It is also a useful analytical tool to improve automation tooling design and transfer motion operational parameters.

From Incremental Change to Full Design/Validation Leap: A Multidisciplinary Approach to Optimize Safety and Crash Performance

Heavy-duty mining trucks at Hitachi are designed to meet ISO ROPS and FOPS safety requirements, while structures must be as lightweight as possible. The presentation will discuss Hitachi’s design and simulation approach, which consists of an integrated multidisciplinary analysis process. Dynamic analyses, multibody dynamics simulations, including flexible bodies and dynamic simulations are methods applied to optimize performance and vehicle safety. The author will present examples such as the optimization of a trolley support structure, a kinematics model of a 100-ton truck and the analysis of a trailing arm. Finally, the author will share his thoughts on the important subject of how simulation can better impact the design.

A Procedure for Performing Tube Hydroforming Simulations

Tube hydroforming simulations can be challenging to perform due to the multiple forming stages involved and the shape variability between those stages. A step-by-step procedure will be presented to approach tube hydroforming projects. The author will also present tips for solving hydroforming simulations using LS-Dyna3D. The tube-bending macro within HyperForm will be leveraged, along with other capabilities within the HyperWorks suite. Some aspects of accurate material representation in hydroforming simulations will also be discussed.

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.
