AI Transforms GM: 15-Hour Simulations Now Take One Minute
1 Jun
Summary
- GM now uses AI to shorten complex simulations from 15 hours to one minute.
- This leap allows for rapid iteration and optimization of vehicle design.
- The technology impacts diverse areas from vehicle handling to factory design.
General Motors is ushering in a new era of engineering, termed the 'third epoch,' by leveraging advanced AI and virtual development tools. This strategic shift is dramatically accelerating the design and development process for vehicles and related technologies.
Historically, engineering relied on empirical, iterative methods. The second age introduced virtual tools like CFD and FEA. Now, the third epoch collapses these functions into a probabilistic approach powered by AI and machine learning, enabling simultaneous optimization of hardware and software.
This transformation is evident in simulation times; FEA runs that once took 15 hours are now completed in under a minute. This speed allows engineers to pump through iterations rapidly, explore a broader set of tests, and optimize performance much more efficiently.
The impact extends beyond core engineering. GM is using these virtual tools for vehicle handling tests, crash performance analysis, HVAC system development, and even designing factories with digital twins. Collaboration with motorsports teams like NASCAR and Formula One further enhances tool development and technology transfer.
This accelerated virtual development allows GM engineers more time for innovation and creative problem-solving, rather than getting bogged down in repetitive tasks. The company is applying these methods across various businesses, including motorsport, energy, batteries, defense, and its lunar program.
