Dear COMSOL community,
I would like to perform a stress analysis on a Synchronous Reluctance Machine in order to investigate the stress and displacement on the iron bridges. The difference in my study with respect to the "standard" stress analysis is that I need to impose boundary layer load which are not standard, besides the trivial rotating frame load which takes into account for the centrifugal force.
In my case the forces I need to impose as load have been computed analytically in an eccentricity study in terms of magnetic forces operating on the rotor at the airgap. Therefore now I need to take the force computed (which is a numerical function with a force value for each angle along the whole periphery of the rotor) and impose it as a boundary load.
Is there a way to establish a boundary load from a set of values? Do I need to split the boundary using several nodes and put one by one my load point by point or there is a way?
I was also thinking to decompose in Fourier series my numerical set of forces along the rotor periphery and assign an analytical expression in terms of Fourier series using the Fourier coefficient. But, what if I have too many coefficients in order to be precise in defining the Boundary load?
I thank you in advance if you have advices about how I could perform this.
I would be really grateful.
Sincerely,
Nicola![]()
