What’s the secret behind 300.000 kilometers on a counter?
The answer is... Durability Engineering
A durable design is more than a trendy word. Durability is strongly related to brand image and thus a crucial selling point. But today’s customers have more on their wish list than a durable vehicle. They also expect a wide variety of vehicle types, a higher quality, at preferably a lower price. The automotive industry is ready to meet these durability expectations and requires top notch road load data acquisition solutions.
When addressing new target markets, the automotive industry often experience challenges generating road data in a timely manner on the one hand and deriving customer correlated driving behavior to set durability targets and cascade them down to subsystem and component level on the other hand. LMS answers:
- LMS Durability testing solutions add another dimension to testing flexibility and efficiency. LMS designed a mobile test unit for truly rugged data acquisition in extreme conditions.
- LMS Durability testing solutions consolidate the acquired load data, analyze durability specific characteristics and apply damage equivalent data reduction. This technology helps to prepare data for reliable simulations and shortens laboratory test cycles and proving ground testing.
Integrating durability engineering into the vehicle systems simulation process is a twofold challenge. It becomes more stringent to analyze the generated transfer loads through a digital or hybrid multibody-based test track simulation, as well as to accurately predict the life of a component. LMS Engineers evaluate fatigue-life and durability performance through a smart combination of test, flexible body and multi-body simulation solutions and FE-based numerical life prediction. LMS answers from any measurement to robust road loads prediction through hybrid of full digital techniques:
- Hybrid load prediction technology allows translating measured road inputs on a predecessor vehicle to equivalent road load data to be applied in simulation models of next generation vehicles.
- Digital road prediction efficiently combines digitized road surface with detailed tire and vehicle models to support digital road loads prediction.
LMS life time prediction technology accurately traces the fatigue performance of each vital chassis component, and efficiently predicts fatigue-life from body structures, over door systems to engine brackets and exhaust lines, for sheet, tube and casted structures. It also guarantees a high degree of accuracy for seam weld and spot weld analyses. Advanced thermal fatigue numerical durability predictions can be applied to engine and powertrain parts.
LMS provides its expertise in durability engineering at all stages of the development process and brings to market a more efficient durability engineering process, supporting the trend of more body variants on fewer platforms. LMS Engineering can take full-vehicle durability responsibility or address durability issues on specific subsystems.
