Coventry-based casting specialist Sarginsons Industries has released the world-first designs which have taken an existing cast automotive subframe that was optimised for weight in 2022 and has reduced it from 28kg to 15kg.
The design shows where excess aluminium has been removed, thereby showing how the AI-driven software can simulate the varying mechanical properties of a part to put the right material in the right place.
Sarginsons said it is aiming to produce the first physical casting using this technology by the summer.
The designs are the early results of the Performance Integrated Vehicle Optimisation Technology project (PIVOT), which Sarginsons is leading with its partners after receiving a £6m matched grant from the Advanced Propulsion Centre and Innovate UK.
MORE FROM ARTIFICIAL INTELLIGENCE
In a statement, Gavin Shipley, technical director at Sarginsons, said: “The designs don’t just look extraordinary, but by being 50 per cent lighter, they are extraordinary.
“We have managed to overcome the complexities of simulating the yield, tensile strength and elongation of cast components. We can now predict, at a point-by-point basis across the entire form of the casting, its mechanical performance. This allows for true vehicle crash performance to be simulated for the first time.
“The ability to simulate and optimise casting performance at such a granular level means we can now produce organic, highly-optimised designs that were previously beyond human imagination.
“The castings are also designed using secondary, fully-recycled aluminium for the first time, meaning that the PIVOT research could also represent the single biggest step forward in vehicular carbon reduction since the advent of the electric car – whilst dramatically reducing the need for environmentally damaging extractive mining.
“The combined effect of all this technology is that we can finally, fully exploit the full potential of liquid metal engineering to create almost any shape or size of component, with no loss of performance.
“That is a really exciting prospect, as we are paving the way for cars, planes, trains and drones to utilise this technology in the future to make them lighter, greener and more cost-effective.”
Cast aluminium parts are stronger and lighter with AI design
That is exactly where real AI can be a help. Unlike the biased chat style versions, which fail the Turing test if pressed hard enough (mind you some...
