• Thermal-mechanical-metallurgical equations coupled with the electromagnetic equations to solve for the electromagnetic properties of the part While not easy to solve, the FORGE® software’s approach to simulation was able to do the job. With the integrated solution, the team could solve for the frequency and intensity of the current required to operate at the resonance state as well as model the influence of the Curie transformation point on the part. A fully integrated solution

adding the generator into the simulation allowed the NTN-SNR team to model the entire magnetic induction hardening process of their bearings. This new capability allowed the entire team more control and understanding of their product and the process.

A Solution through Simulation With a well-defined problem statement and desired goal, the Transvalor team worked with NTN-SNR on a solution. The FORGE® software was well-equipped to tackle NTN-SNR’s problem with minimal modifications. To calculate the frequency and intensity needed for the generator to maintain constant power, FORGE® used an iterative algorithm. This algorithm solved for two sets of equations simultaneously: • Electromagnetic equations solving for power density from induced currents
