Rotor dynamics

Engineering Service + ARMD Software

• Torsional Vibrations

• Lateral Vibrations

• Fluid-Film Bearings

• Rolling Element Bearings

ROTOR DYNAMIC 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).

I am the official cooperation partner of RBTS, Inc. (U.S.A.) (www.rbts.com), which was acquired by Concepts NREC (U.S.A.) in January 2024 to further expand the engineering and software business.

As official cooperation partner, I provide software and engineering support in close coordination with Concepts NREC – usually realized in efficient online meetings.

Advanced Rotating Machinery Dynamics – Software ARMD V6.2

The simulation software „ARMD“ designed by Concepts NREC is a very powerful CAE tool which is distributed and supported in Germany and Europe via my engineering office.

Non-binding LIVE presentations can be arranged individually supported by an online meeting.

The ARMD software packages/modules and software structure:

International Rotor Dynamics Seminars … more than 20 Years

I would also like to inform you on the annual International Rotor Dynamics Seminar & Short Course. This seminar is an offer in close co­opera­tion with my partner Concepts NREC – and it is unique in Europe and well accept­ed by many inter­national atten­dees for more than 20 years.

Please visit the special seminar site for detailed infor­mation on the next online semi­nar including online registration: Information on the next INTERNATIONAL ROTOR DYNAMICS SEMINAR

ARMD Training Courses – Online Training via Cisco Webex

In close cooperation with my partner Concepts NREC I offer an Online ARMD Training Course any time (language: ENGLISH; duration: usually 8 hours in total). Such a course is offered dedi­cated to one of the ARMD packages the customer ordered (ROTLAT, TORSION, BEARINGS). The course is usually structured in two parts on two sub­sequent days directly pre­sented by my US partner.

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