Rotordynamic Software MADYN 2000
Versions 4.2, 4.3 and 4.4 are distributed. Version 4.2 contains a hot spot stability analysis to assess the sensitivity of hot spots (e.g. in fluid bearings → Morton effect). Version 4.3 allows analysing non-linear rolling element bearings (clearance effects, non-linear Hertz'ian pressure). Version 4.4 includes among others new harmonic response analyses (bent shafts, coupling offsets, response to integer and non-integer harmonics, balancing), field plots for fluid film bearing analysis results as well as new export and import capabilities, e.g. for magnetic bearing control design and dynamic bearing supports.
