Designing high quality, reliable products is always a prime motivation for a wide variety of Industries from home appliances to land vehicles. While it is possible to use physical testing to verify durability, it is most efficiently done by applying simulation methods integral to the development process.
Here are a couple Industrial examples for you to glance over:
1. Honda – Vehicle Strength and durability
2. MABE – Designing reliable washing machines
In the past, our colleagues have written some interesting articles such as “Simulation Driven Automotive Closures” and “Analyzing Durability”. If you try to connect the dots here, you will realize that one of the most crucial aspects for predicting durability is getting accurate component loads. The challenge is that in many situations is that these cannot be directly measured experimentally.
This article gives you an insight into how accurate component loads are generated from physical or virtual tests and the different approaches in use today for vehicle durability evaluation.
BasicFEA – released with the HyperWorks 11.0.120 update – is a new HyperMesh user profile offered as part of the HyperWorks Engineering Solutions. It allows users from the novice to expert level to run a broad range of simple analyses, going from CAD to CAE in very few clicks.
When you need a quick solution, yet with the power of HyperMesh behind you, BasicFEA is the answer.
Two University of Stuttgart racing teams recently reported exceptional results from employing HyperWorks tools to simulate vehicle design and reduce the weight of their cars prior to vehicle construction.
The impact of HyperWorks is evident in the victories earned by the Stuttgart teams. In 2011, the Rennteam was rated number one in the Formula Student world rankings and has won 10 single competitions since 2005.
The GreenTeam, with 37 teams participating in the electric category in 2011, placed second in Italy and currently holds third place in the overall worldwide rankings list for the electric competition.
OntoNet™, the world’s first complexity quantification and management system, is now accessible through Altair’s HyperWorks Partner Alliance.
OntoNet™ is a desktop tool that allows engineers to measure the complexity and robustness of components or systems. It processes the results of Monte Carlo Simulations, DOE, optimization or sensitivity analyses to compute the values of system complexity and robustness, enabling engineers to exploit their expansive amounts of existing data to the fullest extent and achieve simpler, more robust designs. It works in conjunction with MAPVIEW™ and produces a report, containing the Complexity Profile of a system and the corresponding System Map.
“If CAE is to cope with the inevitable increase of product complexity, then complexity must enter the CAE loop. High complexity is a prelude to inefficiency and vulnerability; therefore it becomes necessary to use a measure of product complexity as a design attribute, said Dr. Jacek Marczyk, founder and CTO of Ontonix. “Technology developed by Ontonix allows engineers to conceive new solutions and designs while effectively quantifying and managing the risks associated with overly complex systems.”
This update includes many exciting features, enhancements and bug fixes to HyperWorks 11.0 Desktop applications including HyperMesh, HyperView, HyperGraph, MotionView, HyperStudy, HyperMath, Solver Interfaces, Engineering Solutions and Manufacturing Solutions.
“rigidified = ” – a useful flex body attribute
This article serves as an introduction to a recently introduced attribute called ‘Rigidified” for the Flex body statement in MotionSolve (XML). This is an optional Boolean attribute, which allows the user to convert the flex body into a rigid body.
It is recommended that the user has prior knowledge of MotionView Flex body simulation basics and some familiarity with the MotionSolve Solver input format (XML) to take full advantage of this article.
Assigning multiple densities to CAD components
MotionView11.0 brings with itself, a useful option in the already existing Tools > Import CAD or FE feature. Now the user has control over the density of each CAD component in his/her CAD file.
