1Reliability
If a load roller is used to apply strong radial forces to the wheel during rotation, then realistic loaded wheel conditions can be measured, but the measuring apparatus becomes heavy and bulky
Solution Approach 1:
The patent creates a digital copy or model of the wheel (virtual wheel model) and simulates the loading conditions computationally instead of physically. The contour data of the wheel is used to build a model that can be virtually loaded, eliminating the need for heavy physical load rollers while maintaining measurement accuracy.
Solution Approach 2:
The patent replaces the mechanical load roller system with a computational simulation system. Instead of using physical forces and mechanical components to apply load, the invention uses computer-based calculations to simulate the effects of loading on the wheel, substituting mechanical complexity with digital processing.

If physical loading with strong forces is applied to the wheel, then wheel behavior under load can be determined, but physical wear occurs
Solution Approach 1:
The patent creates a digital copy or model of the wheel (virtual wheel model) and simulates the loading conditions computationally instead of physically. The contour data of the wheel is used to build a model that can be virtually loaded, eliminating the need for heavy physical load rollers while maintaining measurement accuracy.
Solution Approach 2:
The patent performs preliminary contour scanning of the wheel to create a digital model before any loading simulation. This preliminary action captures all necessary geometric information, allowing subsequent virtual loading experiments to be performed without physical contact, thus preventing wear during the measurement process.

If the wheel contour is scanned and virtual loading simulation is performed, then heavy equipment is not needed, but complex calculations are required
Solution Approach 1:
The patent replaces the mechanical load roller system with a computational simulation system. Instead of using physical forces and mechanical components to apply load, the invention uses computer-based calculations to simulate the effects of loading on the wheel, substituting mechanical complexity with digital processing.
Solution Approach 2:
The computational system automatically processes the contour data and performs the loading simulations without requiring complex manual setup or intervention. The system self-manages the complex calculations through automated algorithms, making the complexity transparent to the user while keeping the physical apparatus simple and lightweight.

AI summary
The invention relates to a method for contactless determining a behavior of a loaded tyre or wheel, comprising the steps of determining a contour of at least a portion of the tyre or wheel; simulating loading of the tyre or wheel with a virtual loading element bearing against the tyre for at least one rotary position of the wheel on the basis of the determined contour, a displacement of the determined contour caused by the virtual loading element and at least one parameter associated to the tyre or wheel or to a part of the tyre; and determining the behavior of the loaded wheel using the simulation results.
