Предложена новая геометрическая трактовка этих уравнений. На ее основе установлено, что рабочее пространство представляет собой двухпараметрические множества эксцентрических и концентрических окружностей. При отображении таких окружностей в четырехмерное пространство получены два вида гиперповерхностей, которые являются геометрической моделью рабочего пространства манипулятора. Дискриминантами этих гиперповерхностей на гиперплоскости являются две двумерные поверхности. Получены как аналитическое описание этих поверхностей, так и их компьютерные модели. В результате установлено, что границами рабочего пространства на плоскости механизма являются дискриминанты таких поверхностей. Для подтверждения достоверности полученных результатов в качестве примера на дискриминантных поверхностях решена обратная задача кинематики — определены значения обобщенных координат в точках границ рабочего пространства манипулятора для заданных их декартовых координат.</p></abstract><trans-abstract xml:lang="en"><p>A study of the boundaries of the working space of a three-link planar manipulator, specified by analytical equations, is carried out. A new geometric interpretation of these samples is proposed. On its basis, it is established that outer space consists of two-parameter volumes of eccentric and concentric circles. When transforming such environments into four-dimensional space, two types of hypersurfaces are obtained, which represent a geometric model of the manipulator's workspace. The discriminants of these hypersurfaces on the hyperplane are two two-dimensional surfaces. Both an analytical description of these surfaces and their computer models are obtained. As a result, it is established that the boundaries of the working space on the plane of the mechanism are the discriminants of such surfaces. To confirm the reliability of the results obtained, as an example, an inverse kinematics problem is solved on discriminant surfaces — the values of generalized coordinates at the boundary points of the manipulator’s workspace are determined for their given Cartesian coordinates.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>геометрическое моделирование</kwd><kwd>компьютерная модель</kwd><kwd>манипулятор</kwd><kwd>центр схвата</kwd><kwd>рабочее пространство манипулятора</kwd><kwd>гиперповерхность</kwd><kwd>дискриминанта</kwd><kwd>трехзвенный планарный манипулятор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>geometric modeling</kwd><kwd>computer model</kwd><kwd>manipulator</kwd><kwd>gripper center</kwd><kwd>manipulator workspace</kwd><kwd>hypersurface</kwd><kwd>discriminant</kwd><kwd>three-link planar manipulator</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">Duka A.
