3D Presentation of Vibrations of a Compressor Shaft / (c) RBTS

  • Torsional Vibrations

  • Flexural Vibrations

  • Lateral Vibrations

  • Fluid-Film Bearings

  • Rolling Element Bearings

 

 

ROTORDYNAMIC SIMULATIONS (i.e. analysis of flexural and lateral vibrations including bearing influence) are another subject area as part of the engi­neering service. These CAE studies include the calcu­lation of critical speeds and acceptable operating conditions while consider­ing the shaft design and above all the charac­teristics of the ball, roller bearings, or the fluid-film bearings, respectively. The analysis also in­cludes the study of tor­sional vibra­tions as an option.

Starting with smaller studies, which can be realized in a short time, you can „upgrade“ the engi­neering service step by step even up to a complete study, design and configu­ration of complex fluid-film bearings (journal, conical, thrust, tilting-­pad bearings).


Cooperation between Laschet Consulting and RBTSLaschet Consulting
is official cooperation partner of RBTS, Inc. (U.S.A.) (www.rbts.com). We provide software and engineering support in close cooperation with RBTS – usually realized in efficient WebEx meetings.

Advanced Rotating Machinery Dynamics – Software ARMD

The simulation software “ARMD” designed by RBTS is a very powerful CAE tool which is distributed and supported in Germany and Europe by Laschet Consulting. Presentations and training sessions can be arranged individually – usually supported by an online meeting (WebEx).

 

The ARMD software modules:
