DELTA JS AG offers software, engineering and consulting services in the field of rotordynamics. Typically the company deals with high precision machines, whose functioning or service life is affected by even the smallest vibrations.

The program MADYN 2000 ® developed and offered by DELTA JS is a leading software for rotordynamics allowing to simulate complex rotor-gear-bearing systems with all types of bearings (spring and damper bearings, fluid film bearings, active magnetic bearings) and bearing supports.

The company disposes of powerful analysis tools to offer comprehensive engineering and consulting services in the area of rotor dynamics. The experience of DELTA JS covers a wide field of sophisticated machinery such as turbo machines for industrial applications, power generation and propulsion.

Seminars

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 10^th until 12^th 2012.

A magnetic bearing seminar will take place in Zurich on June 13^th and 14^th 2012.
Registration forms are available here.

 

Rotordynamic Software MADYN 2000

Version 3.6 is ready. Main new feature of this version are the automation of analyses (batch), new modelling features for fluid film bearings (among others hydrodynamic pockets), features to support the design of magnetic bearings, possibility to import user programs for certain features as well as many new plotting features. More details are avaiable in the release notes.

 

1^st Middle East Turbomachinery Symposium from February 13^th to 16^th 2011

DELTA JS (Joachim Schmied) was invited to present a case study, which is also described in a paper.

 
8^th International Conference on Rotor Dynamics of the IFToMM in South Korea from September 12^th to 15^th 2010
DELTA JS presented the paper "Nonsynchronous Tilting Pad Bearing Characteristics" by Joachim Schmied (DELTA JS), Alexander Fedorov and Boris Grigoriev (both Polytechnical University Saint Petersburg). This time we did not win the the price for the best paper (Jorgen W. Lund Memorial Award). Nevertheless the paper received a lot of attention. Further papers with pariticipation of DELTA JS were "Rotordynamic Modelling as a Powerful Support Tool for Vibration Analysis on Large Turbomachinery" by Kris Matthys, Koen de Bauw (both Laborelec) and Marco Perucchi (DELTA JS), as well as "Asymmetrical Heating in a Tilting Pad Journal Bearing Causing Shaft Bending" by Boris Grigoriev, Alexander Fedorov (both Polytechnical University Saint Petersburg) and Joachim Schmied (DELTA JS).
