AI Technical Summary

Technical Problem

Existing design methods for simulating wheel bosses suffer from low design confidence and low efficiency. They neglect the size effect of the field strength radius and the mismatch of the damage area morphology, resulting in life prediction errors and low design efficiency.

Method used

The characteristic state vector of the real roulette wheel is extracted by full-size finite element analysis. A multidimensional stress gradient mapping and dynamic field strength correction algorithm are constructed. The geometric dimensions of the simulated part are optimized by volume intersection-to-union (IoU) technology to ensure the consistency of the damage domain shape and the accuracy of the field strength value between the simulated part and the real part.

Benefits of technology

It achieves high-fidelity reproduction of the fatigue failure mechanism of the roulette wheel, significantly improving the accuracy of life prediction and design efficiency, reducing the time from weeks to hours.
