New Al-based technology from Sumitomo Rubber is launched


A New AI-Based Technology Designed to Accelerate the Development of Tyre Performance Sustaining Technology has been released by Sumitomo Rubber Industries, Ltd.  The company said it was pleased to announce that it had completed the development of a new AI-based technology that utilises real-world data on tyre raw materials, as well as advanced analytical data on the internal structures of rubber, to perform a wide range of tasks, including not only precisely estimating rubber properties, but also detecting structural changes that occur during use in order to predict the properties of rubber after use. They call this versatile new technology “Tyre Leap AI Analysis.” Taking full advantage of this groundbreaking technology, the Sumitomo Rubber Group plans to accelerate the development of “Performance Sustaining Technology*1,” one of the key development trends of our “SMART TYRE CONCEPT,” which aims to contribute to the realisation of a sustainable Mobility Society for the future by developing high-performance tyres that provide both safety and peace of mind.

*1. Technology that aims to suppress the degradation of tyre performance that occurs due to wear and the passage of time, allowing tyres to maintain like-new performance for longer.

The rubber used to make tyres is actually a compound composed of many different materials, including polymers (such as natural and synthetic rubber), reinforcing agents (such as carbon black and silica), crosslinking agents and additives. Tyre performance depends on many interlocking factors related to the proportions of these various materials, the structures that they form in combination and so forth. As the internal structures of rubber are exceedingly complex, there are limits to what human beings can accomplish when it comes to analysing them, both in terms of the time required for analysis and the precision of analysis results.

Thus, our newly developed “Tyre Leap AI Analysis”utilises advanced AI-based analysis technology*2 to analyse (for example) electron microscope imagery of tyre rubber compounds in order to achieve high-precision analysis that far exceeds human capabilities, thereby making it possible to derive accurate estimates of rubber properties from structural data found in this imagery. Meanwhile, combining data on the individual raw materials contained in a rubber compound with data on its internal structure allows for even more precise estimates of rubber properties. Further, “Tyre Leap AI Analysis”is also able to detect structural changes that occur during use by comparing used and unused rubber, meaning that this new technology has enormous potential for such future applications as predicting the properties of rubber after use.
