- Training for the use of our software, about design rules and practical vibration phenomena
The next rotordynamic seminar including an additional day for the demonstration of practical rotordynamic analyses with MADYN 2000 will take place in Zurich from October 7th to9th 2020. Registration forms are available here.
The magnetic bearing seminar planned in June is cancelled. Please check here for the content and a new date, which will be fixed end of this year.
The film bearing seminar planned in June is cancelled. Please check here for the content and a new date, which will be fixed end of this year.
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.
