- ПубликацияТолько метаданныеSelection of a Friction Model to Take into Account the Impact on the Dynamics and Positioning Accuracy of Drive Systems(2021) Kreinin, G. V.; Misyurin, S. Y.; Nosova, N. Y.; Nelyubin, A. P.; Мисюрин, Сергей Юрьевич© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.The problem of choosing a friction model for solving the problems of controlling positional systems, primarily with a pneumatic drive, is discussed. Due to their high dynamics, good towing capacity and relatively low price, pneumatic positioning systems are an attractive alternative to electric drives. However, the use of pneumatic systems involves some difficulties caused by the nonlinearities of its individual elements, in particular the flow characteristics of the servo valve, the compressibility of the working fluid, and also the friction acting on the piston. The main goal of this work is to analyze the stability in the interaction of the energy and control units under the influence of friction forces represented by various models. The Karnopp model was considered as one of the models, which has the advantage in describing the interaction with the friction forces in the transition from the state of rest to motion and vice versa.
- ПубликацияТолько метаданныеKinematics and Dynamics of the Spider-Robot Mechanism, Motion Optimization(2021) Kreinin, G. V.; Misyurin, S. Y.; Nosova, N. Y.; Nelyubin, A. P.; Мисюрин, Сергей Юрьевич© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.In this paper, we consider the kinematics and dynamics of a spider robot mechanism with 18 degrees of freedom (six legs). The equations of kinematics and dynamics are written out; and the issue of optimizing the robot’s movement is considered. The robot’s gait is analyzed, in which part of the legs is on the ground and supports the robot, and part of the legs moves in the air. At the first stage for solving this problem, one leg is considered separately, as a kinematic system with open kinematics and with three degrees of freedom. The kinematics equations were presented in matrix form using the principle of rotation of the coordinate system. The dynamics equations are based on Lagrange equations of the second kind. The mass of the legs, reduced to the center of gravity, moments of inertia, moments developed by engines were taken into account, and etc. The conclusions were made about the optimal movement of the leg based on the obtained equation of kinetic energy of the robot’s leg based on the obtained equation of the kinetic energy of the robot leg.

- ПубликацияТолько метаданныеExploring the Workspace of a Robot with Three Degrees of Freedom(2022) Nosova, N. Y.; Misyurin, S. Y.; Мисюрин, Сергей Юрьевич© 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.In this paper, we consider the mechanical part of the robot controlled by artificial intelligence according to three independent coordinates. The solution of kinematics problems is considered. The task is set to determine the size and shape of the workspace of the robot mechanical part based on solving the inverse kinematics under given initial conditions. This is important for solving the planning problem, since all the trajectories of the output link with the working tool (end-effector) of the robot must remain within the obtained working area. It is possible to create quite complex mechanisms of both sequential and parallel structures, but if the working area of this mechanism is small, then their scope of application is significantly reduced. Each kinematic chain of the developed mechanism includes spatial four-links (hinged parallelograms). They are a flat mechanism in which the axes of rotation of the kinematic pairs are located in a plane perpendicular to the axes of their rotation, and all the points of the links describe the trajectories of movement in parallel planes. Thus, the spatial four-link mechanism can be used to transmit both translational motions and to transmit rotation to the output link and/or the working tool.
- ПубликацияТолько метаданныеMulticriteria Optimization of a Hydraulic Lifting Manipulator by the Methods of Criteria Importance Theory(2022) Nelyubin, A. P.; Kreinin, G. V.; Nosova, N. Y.; Misyurin, S. Y.; Мисюрин, Сергей Юрьевич© 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.The article describes the procedure for multicriteria optimization and choosing the best parameter values of a manipulator designed to lift a heavy, bulky load using two parallel and synchronously operating hydraulic drives. Information about the dynamics of the system was obtained by computer simulation of a sufficiently complete dimensionless model. Three characteristics of the system are considered as optimality criteria: imbalance of mass loads on drives, power (size) of drives and synchronization of their operation. To search for feasible solutions to the optimization problem in the parameter space, a sequence of uniformly distributed points was generated. The sets of feasible and Pareto optimal solutions are analyzed using visualization tools in the MOVI program. Within the framework of the mathematical criteria importance theory, expert information on preferences regarding criteria was formalized and refined. In the course of this iterative procedure, the set of feasible solutions was narrowed down to 67, then to 4 alternatives, and in the end one best solution was chosen.
- ПубликацияТолько метаданныеThe Hexabot Robot: Kinematics and Robot Gait Selection(2022) Nelyubin, A. P.; Kreynin, G. V.; Nosova, N. Y.; Misyurin, S. Y.; Chistiy, A. S.; Khokhlov, N. M.; Molchanov, E. M.; Мисюрин, Сергей Юрьевич© 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.The article is devoted to the problems of movement and control of a six-legged walking spider-robot. The direct and inverse problems of kinematics of a spatial mechanism are solved. The motion of a walking six-legged robot Hexabot (robot “spider”) with possibility of realization of different motions is considered. The task is to increase the speed of the robot's movement from one position to another by reducing the dynamic loads on the robot leg, as well as by choosing a more rational dynamically balanced gait. In solving the first part of the work, at the first stage, one leg is considered separately as an open kinematic system with three degrees of freedom. Equations of direct and inverse kinematics are obtained. The motion of the platform (the “body” of the spider) is not considered in this work.
- ПубликацияТолько метаданныеParametric and Structural Optimization of Pneumatic Positioning Actuator(2020) Kreinin, G. V.; Prozhega, M. V.; Misyurin, S. Y.; Nosova, N. Y.; Мисюрин, Сергей Юрьевич© 2020, Springer Nature Switzerland AG.Linear positioning actuators are widely used in industry as a convenient means of positioning objects directly without the use of additional motion conversion mechanisms. A significant place among them is occupied by piston-type hydraulic and pneumatic systems. Their application areas are different due to the difference of their power to weight ratio, as well as performance characteristics. One of the most popular applications of pneumatics is in material and small mass object transportation over short distances. In this sphere pneumatics has obvious advantages in power density, speed output response, ecology, cost and other factors. On the other side, the pneumatic actuator is difficult to control due to the compressibility of the working fluid (air), the nonlinearity in the flow phenomenon, sensitivity to changes in parameters, friction forces and other factors. This work is aimed at finding a compromise solution to the problem of harmonization of the contradictions mentioned above. The task is to find the optimal correlation between the systems parameters, compensating for negative properties and allowing the full use of available opportunities. The solution of the problem is based on the results of modeling the dynamics of the positioning pneumatic actuator, presented in a dimensionless form, including the model of the power drive itself, the control system (controller) and the external effects.
