Abstract
In this paper, the planetary roller screw (PRS) is studied through focusing on the nonlinear factors of clearance and stiffness to constitute a nonlinear model of a PRS based transmission. By combining the focally constructed models of clearances, dynamic calculation of clearance and variable stiffness with those of PRS mechanism and transmission, the proposed nonlinear model is established. After simulating the effects of overall clearance and compliance, performance vector is applied to collating effects of various clearances and compliances across the mechanism for further analysis.
