Simulation for the Automotive industry – Babbage was right, so what are we going to do about it?

Can users of today’s advanced simulation methods for Automotive still learn from sentiments expressed 150 years ago?
On two occasions I have been asked, “Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?” … I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
So said Charles Babbage, widely considered the father of the computer, way back in 1864. He was obviously right – but are we still guilty of the confusion he identifies?
Today’s Automotive industry makes huge investments in simulation to reduce the use of physical prototypes. It’s suggested around 80% of the problems uncovered with physical vehicle prototypes could have been identified earlier in the design process. With prototypes costing around the $1m mark, it’s clear the more issues uncovered within simulation, the better.
Jaguar Land Rover, for example, saved money by releasing their Jaguar EX saloon model without producing a single physical prototype during the aerodynamic engineering process and the company intends to eliminate all physical prototypes from its process by 2020 – only two years from now.
So, simulation is undoubtedly valuable but, remembering Babbage, do we invest enough money and time making sure the inputs to simulation are accurate? In particular, are we sure of the accuracy of one of the most critical inputs: our materials property data?
Ensuring the right materials data inputs to simulation is difficult:
The answer to these problems is to manage materials data systematically and to have a single, accurate source. Then, you need the right tools to generate the materials models for simulation and, finally, these models need to be easily accessed by simulation analysts across the organization.
These are our objectives at Granta with our GRANTA MI:Simulation tools. But however you tackle this issue, you want to be thinking about how to keep Babbage happy with:
Managers involved with material decisions or simulation within the automotive industry may be interested in attending the Automotive Material Intelligence Forum in Munich in May. Consisting of three tracks of information, industry-leading speakers will be discussing Business Processes and PLM, Virtual Product Development, and Materials Challenges.
