TY - JOUR TI - Optimization of a curvilinear thread profile in a planetary roller screw AU - Lisowski, Filip TI - Optimization of a curvilinear thread profile in a planetary roller screw AB - The paper presents an application of the Finite Element Method (FEM) in stress analysis and optimization of thread profiles in cooperation of the roller with the screw in the planetary roller screw mechanism. The problem of the roller and the screw threads cooperation as well as related geometrical parameters were described. The optimization problem was formulated with the aim of obtaining a better effort of threads and lower contact pressure depending on the geometry.
