title = "Elasto-plastic contact characteristics of the planetary roller screw mechanism",
abstract = "A finite element method is used to model elasto-plastic contact problems in the planetary roller screw mechanism and the effects of the profile radius of the roller thread on contact characteristics are investigated. Three different loads and twelve profile radii are chosen and the results show that the contact stresses and contact deformations decrease with an increase in the profile radius. It is interesting to note that the contact deformation of the roller thread is about twice the deformation of the screw thread. Furthermore, the relative errors of the maximum stresses are analyzed and the load distributions among threads display a more non-uniform trend with an increase in the applied load. Under a high applied load, the maximum contact stresses of the screw threads occur on the second threads, which indicates the failure of first threads. The simulation processes in this work can be used to predict the rated load of the planetary roller screw mechanism.",
