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.

Non-binding LIVE presentations can be arranged individually supported by an online meeting (WebEx). There is also an option to download a “demonstration version” of ARMD for free – just to get a better “look & like” feeling.

 

The ARMD software modules and software structure:

ARMD Training Courses – Online Training via WebEx

In close cooperation with our partner RBTS we offer an Online ARMD Training Course (via WebEx) any time (language: ENGLISH; duration: usually 8 hours in total). Such a course is offered dedi­cated to one of the ARMD major modules (packages) the customer ordered (i.e. ROTLAT, TORSION, BEARINGS). The course is usually structured in two parts on two sub­sequent days directly presented by RBTS (U.S.A.):

  1. Basic Training covering the basic technologies concerning dynamics in rotating machinery
    Duration: 4 hours concerning one of the ARMD packages ROTLAT, TORSION, BEARINGS
  2. Advanced Training referring to the software handling in detail; presentation of various general applications and case studies (Note: This is NOT a project related customer training.)
    Duration: 4 hours concerning the ARMD software handling (current release) and presenting typical (general) applications and selected case studies.

Due to the time-zone shift such a course can only start at 08:00 a.m. or 09:00 a.m. US time (at the earliest); i.e. for central Europe: training start not earlier than 14:00 or 15:00 (CET) in the afternoon.

Depending on customer demands, such a training course can be structured individually according to your demands. Please contact us.

Independent of a software training course we also offer a custom-tailored engineering service concerning your current project. Please send us your inquiry (submission of your inquiry).
