Tribo-X and Ansys


In order to expand the applicability of our Tribo-X solver and make it accessible to a wider range of customers, we have been working with our partner Ansys for many years. The results of this partnership are the tools Tribo-X inside Ansys for carrying out individual bearing analyses and Tribo-X for Ansys Motion for carrying out system analyses taking several journal bearings into account. With the help of the resulting solutions, we are expanding the application possibilities of the Tribo-X solver and offering the user a familiar operating environment. Thanks to our status as an Ansys Technology Partner, we are in constant communication with Ansys and work on the ongoing further development of the solutions.

Tribo-X inside AnsysTribo-X inside Ansys

With the integration of the Tribo-X journal bearing module into Ansys Workbench, in cooperation with our development and distribution partner CADFEM, the Tribo-X inside Ansys extension has been developed, which allows the convenient calculation of lubricated journal bearings with Ansys Mechanical. The basis of the bearing analysis is a CAD bearing model, in which the gap area is automatically detected. The description of the geometry and load of the bearing is parametric in the Workbench project tree. The parameterization enables automated sensitivity and optimization analyses of the bearing. These analyses can be supported by Ansys DesignXplorer or Ansys optiSLang.


Tribo-X inside Ansys



  • short calculation times despite high degree of detailing
  • basis of the bearing analysis is a CAD model with arbitrary gap geometry
  • consideration of elastic deformations of the bearing and their effect on the gap geometry
  • complete simulation of the Stribeck curve by considering mixed friction
  • identification of speed- and load-dependent bearing coefficients
  • fully parametric workflow



Seminars for Tribo-X inside Ansys

With Tribo-X inside Ansys, CADFEM and Tribo Technologies have developed a solution that enables convenient and efficient calculation of hydrodynamic radial bearings in Ansys Workbench. In this seminar, you will learn which properties significantly determine the operating behavior of a radial bearing and what role is played by elastic deformations, deviations in shape and position, as well as thermal effects. In addition, you will gain knowledge on how the mixed friction state of a bearing can be evaluated. Through an operating-point-dependent determination of bearing coefficients, you will be able to better understand the vibration behavior of plain bearing shafts. A parameterization of the bearing model allows you to make a holistic optimization of the shaft-bearing housing system for the respective application.

Tribo-X for Ansys MotionTribo-X for Ansys Motion

Tribo‑X for Ansys Motion combines the advantages of the journal bearing module of Tribo-X with the multi-body simulation in Ansys Motion to enable you to perform calculations of an entire application with one or more journal bearings in dynamically loaded systems.

Thanks to our close cooperation with Ansys, we can ensure a robust and powerful integration of our solver in Ansys Motion. Tribo‑X for Ansys Motion enables the user to accurately model journal bearings, taking into account elastic deformations, surface roughness and lubricant supply geometries. At the same time, the combination of the high-performance solvers of Ansys Motion and Tribo‑X guarantees short calculation times to accelerate the development of your products. Tribo‑X for Ansys Motion is an integral part of the Drivetrain Toolkit and is directly available to you after the installation of Ansys Motion.
