Numerical simulation of deformation of flexible ring on power rolling ring

In this paper, the influence of the deformation of the flexible ring on the performance of the power rolling ring is studied by the finite element simulation method. The results show that the maximum stress of the flexible ring is concentrated in the contact area with the inner and outer conductive rings, and the maximum bending stress increases significantly from 93.5 MPa to 217 MPa with the increase of deformation from 0.3 mm to 0.7 mm. On the other hand, with the increase of deformation, the oscillation of the velocity curve of the probe point on the flexible ring is weakened and tends to be smooth, indicating that the stability of the motion is gradually improved. The research reveals that increasing the deformation can improve the motion stability and also lead to a significant increase in the contact stress, which provides an important basis for the balance design between structural reliability and motion stability of the power rolling ring.
