“…This movement process of the piston is continued until the stroke end of the piston. This characteristic is called "stick-slip" motion and has been observed in pneumatic cylinders (Sakiichi et al, 1988;Peng et al, 2012) and in other mechanisms (Mate et al, 1987;Lampaert et al, 2004;Landolsi et al, 2009). This motion of the piston can be explained that when air is supplied to the chamber 1, air is compressed and the pressure p 1 is increased (in Fig.…”

“…Classical friction models that describe the steady-state relation between velocity and friction force, which can be characterized by the viscous and Coulomb friction with Stribeck effect combination have been proposed (Hibi and Ichikawa, 1977;Armstrong, 1991;Armstrong et al, 1994;Pennestrì et al, 2016;Marques et al, 2016Marques et al, , 2019Brown and McPhee, 2016). However, some friction behaviours cannot be captured by these classical friction models, as for example, hys-teretic behaviour with oscillating velocity, stiction behaviour and breakaway-force variations (Armstrong et al, 1994).…”

Abstract. This study examines effects of three friction models: a steady-state friction model (SS model), the LuGre model (LG model), and the revised LuGre model (RLG model) on the motion simulation accuracy of a pneumatic cylinder. An experimental set-up of an electro-pneumatic servo system is built, and characteristics of the piston position, the pressures in the two-cylinder chambers and the friction force are measured and calculated under different control inputs to the proportional flow control valves. Mathematical model of the electro-pneumatic servo system is derived, and simulations are carried out under the same conditions as the experiments. Comparisons between measured characteristics and simulated ones show that the RLG model can give the best agreement among the three friction models while the LG model can only simulate partly the stick-slip motion of the piston at low velocities. The comparison results also show that the SS model used in this study is unable to simulate the stick-slip motion as well as creates much oscillations in the friction force characteristics at low velocities.

“…In this study, the frictional interactions of joints and moving parts and flexibility of the links are neglected. Studies on various friction models with verified experimental data [17][18][19][20][21] and studies on hysteresis including structural flexibility or clearances of the joints have been continuously conducted [21][22][23][24][25]. Following to this state of art, the causes of link hysteresis will be dealt with and a sophisticated model including friction model of the joints will be developed in the future.…”

The variable guide vanes (VGV) of gas turbine engines are commonly utilized to expand operating range and to improve efficiency of the compressor. Guiding air flow using the VGVs in the compressor prevents aerodynamic instability by making proper incidence angle to the blades. In this study, we dealt with rig-type three-stages VGVs for developed engine tests. The three link mechanism of VGVs are linked to each other with two hydraulic actuators, and inevitably, induced hysteresis exists between vane rotations and actuators strokes, due to links with non-fully constrained degree of freedoms for easy installation and instrumentation, as well. Therefore, the adjustment of each VGVs link mechanism is required to satisfy vane angle demands. To adjust coupled three-stages VGVs link mechanism, an analytical VGV-link kinematic model was derived, and effects of two adjusting parameters (lengths of bell cranks and vertical links) were discovered. Lastly, we obtained two vane angle schedule curves from the experiments according to link moving directions, and applied them to the engine controller to minimize hysteresis of the variable inlet guide vane (VIGV). The proposed VGV adjusting and controlling method can be simply applied to the pre-designed or pre-manufactured VGVs system without mechanical compensation or additional cost.

“…The contact parameters of the ANN input are derived from a positive pressure (Hunt–Crossley) model and a friction (LuGre) model, which are caused by the load and driving torque qw of walking wheel and describe the influence of relative contact indentation, normal velocity and tangential velocity on the contact force. These contact models appear to be the most accepted in the scientific community being the most widely used, and here we list the Hunt–Crossley 25–27 and LuGre 28–30 formulas (1) and (2) only where Fn is the normal contact force, K is the contact-stiffness parameter, χ=3(1-cr)K/2crδ·0 is the hysteresis damping factor which is intended for use in a contact between softer materials that have a smaller coefficient of restitution cr, and more elastic contacts with higher values of energy dissipation. These types of contact properties can be found in wheel-cable coupling; δ·0 is the initial relative contact velocity in the normal direction.…”

In order to enhance sampling efficiency and security when robot maintains power transmission line (PTL), this article develops a new approach for the rigid-flexible coupling dynamics of robot/PTL system, which decouples the large system into two small systems and solves them separately by estimating the contact force. The robot is modelled as a system of rigid bodies by screw theory, while the PTL system is modelled using absolute node coordinate formulation (ANCF). The integration of screw theory, ANCF and contact estimator trained by artificial neural network has not been accomplished before in the literature. The main contribution of this paper is to achieve this integration with the goal of developing a new and general approach for the nonlinear dynamic analysis of the interaction of the rigid maintenance robot with flexible PTL cable. A simplified two-dimensional example is used to compute the effect of the robot/PTL interaction under different operating conditions to have an understanding of the coupling approach between the two systems. A more detailed three-dimensional model was developed, and the results obtained validate the utility and effectiveness of our approach.
