Virtual design of Cadillac Lyriq cuts dev time and ensures quality

Cadillac Mike says it’s actually the opposite case their deep understanding of materials, loads, how parts interact with each other along with the ability to run hundreds, sometimes thousands of durability tests has engineers “accounting for variations we could never imagine before.” A notable example is the tough one-quarter overlap crash test where engineers can crash a digital vehicle over and over, gather vast amounts of data and modify parts in real time. The old way: run the prototype into the barrier, examine the wreck, glean what’s needed and send it to the scrap heap. And yes, some virtual crash results are now being accepted as official.

Virtual design of Cadillac LYRIQ cuts development time and ensures quality

Article content General Motors engineer Mike Anderson works with computers. A lot. In his 28 years with GM he has worn many hats, but now is the Executive Director of Global Virtual Design, Development and Validation. In short, Anderson is at the pointy end of a new automotive frontier, with the upcoming Cadillac LYRIQ BEV (battery electric vehicle) leading the GM wagon train. With the exponential increase of computing power comes the capacity to sidestep many of the production processes of yore that involved building prototype vehicles, testing parts, breaking parts, redesigning parts, driving millions of test miles, and so on. All time consuming, costly and inefficient. Granted this has been the way for over 100 years, but Anderson says we are now at a tipping point where engineers can design and fully test almost any part of a vehicle virtually before the piece is ever manufactured.
