The load distribution model of the planetary roller screw mechanism (PRSM) is established on the basis of Hertz contact theory. The objective is to obtain a friction torque model of the PRSM in roller jamming. An example is provided to calculate the friction torque of the PRSM in roller jamming. Thereafter, the transmission efficiency is calculated. A static structural analysis is performed using the finite element method to estimate the contact stress between the threads of the PRSM components. Computational results indirectly reveal that roller jamming exerts considerable influence on the friction torque of the PRSM. Results show that the friction torque of the planetary roller screw increases when the roller is jammed and the wear of the parts is accelerated. This condition leads to structural failure. The results of this study can serve as a foundation for electromechanical actuation systems, which can be useful in designing antijamming systems for safety-critical aircraft applications.

“…As a newly developed self-contained power device, the electro-hydrostatic actuator (EHA) has been successfully applied in the field of aerospace, such as primary flight control, landing gears, thrust vector control, and engine actuation systems (Alle, Hiremath, Makaram, Subramaniam, & Talukdar, 2016;Maré & Fu, 2017). In recent years, EHAs also seek potential applications in other fields, such as robotics, wind turbines, and transportation vehicles (Karanović, Jocanović, & Jovanović, 2014).…”

Raising the rotational speed of electro-hydrostatic actuator (EHA) pumps is a useful way to improve their power density. However, gaseous cavitation tends to occur in the displacement chambers at high speed, reducing the effective delivery flow rate of EHA pumps. It is a common approach to reduce the gaseous cavitation by increasing the inlet pressure. However, this conventional approach requires additional devices to boost the inlet line, which decreases the EHA pump's power density. The contribution of this study is to reduce the gaseous cavitation by introducing inclined cylinder block ports for EHA pumps, which only modifies the cylinder ports and needs no additional devices. A computational fluid dynamics (CFD) model was developed to investigate the effects of the inclined direction of cylinder ports on the gaseous cavitation. The simulation results showed that the inwardinclined design of cylinder ports could effectively decrease the gaseous cavitation using centrifugal effects of rotating fluid. Compared with a standard cylinder block, the cylinder block with inwardinclined ports could increase the effective delivery flow rate by 4% at an inlet pressure of 1 MPa and a rotational speed of 20,000 r/min.

“…As the carrier of PBW, the EHA a hydraulic actuator driven by a dedicated pump, rather than a hydraulic network, which drives the pump to control the actuating components by adjusting the motor speed. Compared to conventional hydraulic actuators, the EHA is a typical mechatronic system with the advantages of high-power density, low load and easy modularization, which emphasizes the integration and synergy in specific domains such as mechanics, electronics, controls and hydraulics (Charles, 2017;Li, 2007). But the EHA also presents more challenges in some aspects.…”

“…The latter modeling method can make the model more detailed and accurate, using a variety of commercialized multidomain and system-level simulation packages. For example, the performance analysis in normal and failure modes can be achieved by co-simulation based on AMESim and Matlab (Ji et al, 2009). However, a single discipline-oriented multi-program combination often requires more effort to achieve the optimal results that a unified model system can achieve, which can lead to complexity in modeling and simulation.…”

Electro-hydrostatic actuator (EHA) is a new trend in the more electric aircraft related research works and engineering applications. As a high-performance mechatronics product, however, the physical effects of actuator behavior are multidisciplinary, coupled and strongly nonlinear. Although many commercialized multi-domain and system-level simulation packages exist, they are rarely considered and analyzed as a whole, lacking of a unified model architecture, efficient modeling forms, and comprehensive simulation verification. In this paper, Modelica is used to build a multi-domain virtual prototype of the dual redundant electro-hydrostatic actuation system (DREHAS) that consists of two EHAs in parallel, which supports multiview modeling and interdisciplinary application of the system. Finally, a simulation application case of the elevator actuation system is presented to demonstrate the effective role of Modelica models in system modeling and evaluation.
