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.

Product design in today’s environment requires careful attention to all aspects of the design, including such issues as sustainability, recyclability and durability of the product. Durability of ground vehicles can be particularly challenging because of the way the vehicle is used and the roads on which the vehicle is driven and the product design can change significantly during both the design phase and the product lifecycle. Testing the product is the most common way to verify durability, but testing is also expensive and time-consuming. Virtual durability testing methods in today’s computing environment offer rapid, repeatable predictions of the loads a vehicle will experience and the resulting life that the product will have when put into service.

Altair’s new Durability Director provides a comprehensive, customizable and automated approach for managing the entire durability simulation process. The durability analysis process poses a series of complex and labor intensive challenges in dealing with the large amount of simulation runs across testing, multi-body dynamics, finite element and fatigue groups. The Durability Director environment easily handles the flow of information across these analysis stages and automates the overall analysis process while remaining open to third party solver solutions to seamlessly integrate into any simulation setting.
nCode DesignLife is a leading CAE solution for fatigue life prediction from finite element results. DesignLife enables engineers to go beyond simplified stress analysis and avoid under- or over-designing products by simulating actual loading conditions. DesignLife was recently used in collaboration with an alpha version of Altair’s Durability Director for the Durability Overnight project; an undertaking where an entire durability simulation was achieved in only a few hours.
Durability Director supports the fatigue analysis process by incorporating the management of finite element and multi-body dynamic simulation jobs Altair plans to support nCode DesignLife for use with Durability Director in the future.
HyperWorks users can gain access to DesignLife through the HyperWorks Partner Alliance, a program which allows customers to utilize their previously acquired HyperWorks Units to access a growing suite of third-party solutions at no incremental cost.
