The rotordynamic seminar including an additional day for the demonstration of practical rotordynamic analyses with MADYN 2000, which was planned in Zurich from May 6th to 8th 2020, is CANCELLED due to the virus situation. Please check here for new dates, which will be fixed, once the situation is clearer.
The next magnetic bearing seminar will be held in Zurich on June 16th and 17th 2020. Registration forms will be available here.
The next film bearing seminar will take place in Zurich on June 18th and 19th 2020. Registration forms will be available here.
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.
