Part of my design project requires that I design two coaxial output shafts. I've gone through and calculated the inner shaft based on deflection and Goodman fatigue criterion. The problem now is this: the other output shaft must be a hollow shaft that shares its axis with the interior shaft. All of the fatigue analysis I've done to estimate shaft sizing thus far is based on solid shaft design where solid dimension 'd' is the parameter being solved for. I can determine an approximate sizing based on bearing deflections but that's it for now. Any suggestions?(adsbygoogle = window.adsbygoogle || []).push({});
