![عکس صفحه اول مقاله: Study on Friction Torque Loading with an Electro-hydraulic Load Simulator Study on Friction Torque Loading with an Electro-hydraulic Load Simulator](/preview/png/758025.png)
This article, in order to precisely impose friction on aircraft and weapon actuation systems, presents a new friction loading method characteristic of “torque-zero velocity” switching control with an electro-hydraulic load simulator. As the general Stribeck friction model has little related to static friction, it proposes a “torque-zero velocity” switcher, in which a zero-velocity controller is developed to load the static friction and a torque controller the kinetic friction. With the help of mathematical modeling, this article designs a “torque-zero velocity” switching controller and, correspondingly, provides a “dual-threshold judgment” algorithm. Simulation results indicate that the proposed method can be successfully used to carry out the static and kinetic friction simulation with an electro-hydraulic load simulator.
