However, who manages to do it right, save a fair amount of development and testing costs.
We stand for precision in the finite element simulation of ball screws.
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)
