• darkblurbg
    Based on specialized macros for Ansys we
    generate highly accurate finite element models and
    simulations of your ballscrew drives.
  • darkblurbg
    Parametric, optimized FE models: the spindle, nut
    and balls are assembled automatically
    on a modular basis.
  • darkblurbg
    The finite element mesh is strongly
    refined only at the contact points. We compute
    smooth and highly accurate contact stresses.
  • darkblurbg
    Contact stresses are determined
    with high accuracy in each
    contact point.
  • darkblurbg
    Even in a mounted state and
    under combined load we can compute
    contact rpessures and forces.

Finite element simulation of ballscrews is not easier than manufacturing

However, who manages to do it right, save a fair amount of development and testing costs.

Does your company stand for precision in the manufacturing of ball screws?

We stand for precision in the finite element simulation of ball screws.

Our core competence:

3D modeling and simulation of ball screws in the finite element software ANSYS

Correct modeling of all contact points between the balls and the raceway

Simulation with different preload classes

Computation of contact stresses in each ball contact point

More accurate life calculation as possible with DIN standard, as ball contact forces can also be determined at combined load.

Visualization of the change in contact angle with increasing load

Determination the overall stiffness in all relevant degrees of freedom (axial, radial, torsion)

Consideration of the mounted state (supports, bearings)

Computation of the deformations and stresses on combined load (axial + radial + torsion)

Our customers on the FE-simulation of ball screws from Meshparts:

Kammerer Gewindetechnik GmbH

Questions about ballscrew drives can often only by simulation beantworten. The efficiency and quality of the FE models of Meshparts are a valuable support.

A. Berger GmbH & Co. Präzisions-Maschinenbauteile

When designing a new, dynamically heavily loaded ball screw with double nut we wanted to achieve in relation to the standard calculation higher security. Meshparts has assisted with the necessary simulation tests. Thanks to the extremely detailed finite element models, we could also easily evaluate the load-dependent change in contact angle for each ball in the model.
