We selected the main parameters for a new layout of a centrifugal installation featuring a linear motor and magnetic suspension. Since existing test benches for simulating linear accelerations have a range of disadvantages, we propose to consider an alternative to the classical layout, in particular, to reject the rotary link and replace it by a ring-like path structure with a linear motor, along which a trolley carrying the object under investigation will move on a magnetic suspension. We analysed various spatial stabilisation systems for the trolley moving at high velocities. We defined the key initial data, taking into account descent into planetary atmospheres, design specifics of products subjected to G-forces and existing centrifugal installations. We computed the parameters of a magnetic suspension based on high-temperature superconducting yttrium ceramics and electrical engineering parameters of the linear motor, and carried out strength calculations for the movable part of the test bench using the Femap with NX Nastran software package, accounting for the operational loads intended. The paper presents an option for implementing a new structural layout of an experimental installation that ensures linear acceleration testing in various operation modes

Introduction. The paper researches the sphere of paving with a roller. The authors describe the current situation in the asphalt concrete’s application as a road surface. Moreover, the authors conduct the excursion into the history of material. The paper presents the preconditions that justify the need for creating recommendations, schemes and methods for experimental study of the working body and material under laboratory conditions of various kinds. The aim of the study is to create the stand concept and methods for experimental research of the roller’s working body in the laboratory.Materials and methods. The paper described a laboratory stand for experiments in the sphere of roller’s working equipment. The authors demonstrated the construction made of a base, a stiffener box, guides and a movable part with a frame and equipment, suspended above the compacted material’s container.Results. As a result, the authors presented the detailed methodology for conducting experiments and recommendations for its transformation in the considered sphere. The paper showed all the necessary data for the design, construction of the test bench and experiments with the roller’s working equipment. Discussion and conclusions. Researchers, especially beginners, receive an additional tool for study of dependencies and phenomena that occur during compaction of material by the roller. Therefore, the authors develops the scheme for the research of the roller’s working body in small area conditions and in extensive laboratories.

The paper considers the task of simulation quadcopter motion control in vir-tual environment systems. The proposed solution of this task is based on the application of a mathematical model of quadcopter dynamics, in which quaternion and axis-angle representation of the attitude are used. In this work, a feedback linearization method for the equations of quadcopter and its elec-tric motors dynamics is proposed to control the quadcopter. With the application of this approach, quadcopter motion is achieved by the obtained expressions for linear acceleration and the desired quaternion. The proposed methods and approaches for quadcopter simulation were implemented in the software package of virtual environment and tested using examples of the motion of a quadcopter model along a given path.

Launcher is widely used in rescue and delivering items. On the basis of the electromagnetic theory, magnetic suspension principle and linear motor theory, we put forward the idea of magnetic suspension launcher. Through the theoretical research and simulation analysis, an in- depth study is also given to the distribution of the electromagnetic field and other influential factors concerning the propelling system, which provides the basis for the design of magnetic suspension launcher.
