Rotordynamic Software MADYN 2000
Version 4.5 is distributed. Highlights of the latest versions are the hot spot stability analysis to assess the sensitivity of hot spots (e.g. in fluid bearings → Morton effect), non-linear rolling element bearings (clearance effects, non-linear Hertz'ian pressure), new harmonic response analyses (bent shafts, coupling offsets, response to integer and non-integer harmonics, balancing), analysis of seal coefficients with a CFD solver, further simplifications of the process of analyses with fluid film bearings and improvements of the robustness of complex models with many connections.
