В настоящее время широкое распространение получают экзоскелеты, существенно повышающие возможности человека в части облегчения движения, переноса тяжестей и различных видов деятельности, требующих значительных усилий. Особенно эффективными оказываются экзоске-леты, позволяющие осуществлять сложные виды движения как нижних, так и верхних конечностей, что существенно расширяет возможности человека при выполнении разгрузочно-погрузочных работ. Сравнительно недавно начались разработки экзоскелетов, в которых находят применение элементы гравитационной компенсации, поэтому проведение исследований энергетических затрат в процессе подъема груза и изучение влияния гравитационных компенсаторов на величину моментов, создаваемых электроприводами бедренного и коленного шарниров, являются актуальными и определяются из данной работы.</p></sec><sec><title>Методы</title><p>Методы. Для решения поставленных задач использовались методы системного анализа, проектирования биотехнических систем, теории управления, теории механизмов и машин, методы математического моделирования динамических систем, методы оптимального планирования и проектирования. При создании программных продуктов использованы математические пакеты Matlab/Simulink.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что применение гравитационных компенсаторов позволяет значительно снизить нагрузку на электроприводы. Движение груза происходит за счет работы двигателей, расположенных в зоне голеностопного, коленного и бедренного суставов. Так как при подъеме груза движение экзоскелета происходит в сагиттальной плоскости, то положение звеньев экзоскелета в пространстве определяется четырьмя независимыми параметрами.</p></sec><sec><title>Заключение</title><p>Заключение. Разработана математическая модель подъема груза человеком в экзоскелете. Выполнено математическое моделирование процесса подъема груза с помощью электроприводов экзоскелета. Особое внимание уделено изучению влияния гравитационных компенсаторов на величину моментов, создаваемых электроприводами бедренного и коленного шарниров. Показано, что применение гравитационных компенсаторов позволяет значительно снизить нагрузку на электроприводы. Также проведено исследование энергетических затрат в процессе подъема груза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of research</title><p>Purpose of research. Currently, exoskeletons are getting widespread use. They enhance human capabilities in terms of ease of movement, carrying loads and different types of activities that require considerable effort. Especially effective are those exoskeletons that make it possible to make complex types of movement of both for the lower and upper limbs, which significantly expands the capabilities of a person when performing loading and unloading operations. Relatively recently, they have started the development of exoskeletons which use the elements of gravity compensation. Therfore, the study of energy costs in the process of load lifting and the study of gravitational compensators influence on the magnitude of moments made by the electric drives of the femoral and knee joints, is relevant and is revealed in this paper.</p></sec><sec><title>Methods</title><p>Methods. Methods of system analysis, design of biotechnical systems, control theory, theory of mechanisms and machines, methods of mathematical modeling of dynamic systems, methods of optimal planning and design were used to solve the problems. Mathematical packages Matlab/Simulink were used to make software products.</p></sec><sec><title>Results</title><p>Results. The study shows that the use of gravity compensators can significantly reduce the load on electrodrives. The movement of load is due to the operation of engines located in the area of ankle, knee and thigh joints. Since the movement of the exoskeleton occurs in the sagittal plane during load lifting, the position of the exoskeleton links in space is determined by four independent parameters.</p></sec><sec><title>Conclusion</title><p>Conclusion. The mathematical model of load lifting by a man in an exoskeleton has been developed. Mathematical modeling of the process of load lifting with the help of exoskeleton electric drives has been made. A special attention is paid to the study of gravitational compensators influence on the magnitude of moments created by the electric drives of femoral and knee joints. It shows that the use of gravity compensators can significantly reduce the load on electric drives. Also, the study of energy costs in the process of load lifting has been conducted.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>экзоскелет</kwd><kwd>гравитационная компенсация</kwd><kwd>подъем груза</kwd><kwd>математическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>exoskeleton</kwd><kwd>gravity compensation</kwd><kwd>load lifting</kwd><kwd>mathematical model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Yatsun S., Savin S., Yatsun A., Turlapov R., Adaptive control system for exoskeleton performing sit-to-stand motion.
