Our Software Solutions

The industry is facing ever growing challenges. These include, above all, increasing specialization, ever shorter development times and rising cost pressure. At the same time, ever higher customer requirements must be met for increasingly individualized and ever more complex products. Our engineering competence in the development of precise software products will help you on the way to an optimized development and use of air-lubricated bearings with regard to static and dynamic properties of the bearing.

100% Self-developed

All our numerical tools are developed by sadap itself, without interfacing with other commercial tools such as CFD or FEM programs on the market. Our software simplifies and speeds up the calculation of the behavior of a rotor and various bearings at the ends of the rotor. The simulation program is composed of the basic program, which calculates the behavior of the rotor, and the program module, which simulates the respective type of bearing.

Flexible Structure

The simulation program essentially consists of the basic program, which calculates the behavior of the rotor, and various additional modules that simulate different types of bearings.

Optimized Calculation Ratio

Our software packages simplify and speed up the calculation of the behavior of a rotor and various bearings connected to the rotor that support both radial and axial loads. But that’s not all. With SADAP software products, it is important that the calculation ratio (accuracy / calculation time) remains optimized.

Consideration of Various Effects

The simulation of rotor bearing properties is a challenging subject, since it involves complicated physics with many influencing factors. Therefore, a reliable and accurate simulation procedure requires the consideration of the mentioned factors in an appropriate way, so that no influencing factor is neglected. The offered numerical tools allow to take into account various physical effects in the simulation of bearing properties, such as:

  • The damping effect occured due to the frictional and viscoelastic characteristics of foil material (in the case of foil bearings).
  • The damping characteristics of the bearings coupled with the rotor
  • Influence of excitation frequencies on stiffnesses and damping coefficients
