The electromechanical brake (EMB) is expected to be utilized for future brake systems due to its many advantages. In this paper, keeping commercialization of the EMB in mind, a new EMB clamping force controller is proposed to overcome the limitations of the existing controller, namely, the extra cost for sensor installation and response delay. To design the controller, both mechanical parts and electrical parts in the EMB have to be mathematically analyzed. Also, dynamic models, clamping force, and friction torque are estimated to generate some feed-forward terms of the controller. With an estimation of the contact point where brake pads start to come into contact with a disk wheel, the clamping force is expressed as a polynomial curve versus the motor angle. The estimated clamping force is evaluated in comparison with measured values by a load cell. The proposed controller is based on an adaptive sliding mode control method with an adaptive law reducing errors of the friction torque model. Lastly, the performance of the entire control system is compared with that of the existing controller on a test bench.

With the rapid development of all electric mechanical equipment in the fields of industrial application, aerospace engineering, and national defense, planetary roller screw mechanism has attracted much attention as a new type actuator of electro-mechanical actuator system. This report systematically reviews previous large number of researches as well as new advancements on five types of planetary roller screw mechanisms from both available literatures and studies presented. Firstly, the general structure, merits, limitations, and the application of five types of planetary roller screw mechanisms are summarized. Then, the development state of the planetary roller screw mechanisms is elaborated in the three aspects: parameter design, contact properties, and performance analysis. Common problems and tendencies of theoretical analysis and calculation models are analyzed. Finally, the research directions and methods in the future on planetary roller screw mechanism are discussed. Key technologies and research challenges are presented in terms of multi-pair dynamic contact and multi-body vibration of system, and the development prospects for various planetary roller screw mechanisms in all electric mechanical equipment are summed up.

“…Considering the elastic contacts between parts, Morozov et al (2017) proposed a dynamic model of the PRSM to calculate the natural frequencies of the mechanism and a linear electromechanical actuator with the PRSM. Ma et al (2017) proposed a dynamic model of PRSM based on the bond graph theory that accounts for friction forces, axial clearances, and the stiffness of the screw. Qiao et al (2017) developed a dynamic model of the inverted PRSM in AMESim software, and the model was used to analyse the dynamic response of electromechanical brake system.…”

Abstract. A rigid-body dynamic model of multi-stage planetary roller screw mechanism (multi-stage PRSM) is proposed in this paper. The structure of multi-stage PRSM is introduced and the motion analysis is presented. The total kinetic energy of the mechanism is calculated. The rotation of the screws and carriers is chosen as generalized degrees of freedom. The generalized forces and motion equations of multi-stage PRSM are derived using the Lagrange method. The transient and steady-state behaviours of multi-stage PRSM are simulated, followed by an analysis of the influence of friction coefficients and thread pitches on the motion and forces acting on the multi-stage PRSM. Taking a two-stage PRSM as an example, the simulation results show that the friction coefficient between screw #1 and screw #2 has a slight effect on efficiency and rotational velocity ratios of carriers to screws. When the sum of the pitches of screws is a constant, the axial component of contact force between screw #1 and roller #1 decreases with the increase in the pitch of screw #1.
