VL - 21 IS - 1 SE - Research Article DO - 10.15625/0866-7136/9986 UR - https://vjs.ac.vn/index.php/vjmech/article/view/9986 SP - 45-56 AB - <p>In [3, 4, 5] the form of equations of motion in holonomic coordinates has constructed. The equations obtained give an effective tool for investigating complicated systems.</p> <p>In the present paper the form of equations of motion is written in quasi-coordinates. These equations are solved with respect to quasi-accelerations, which allow to define the motion of a holonomic and nonholonomic systems by a closed set of algebraic – differential equations. The reaction forces of constraints imposed on the system under consideration are calculated by means of a simple algorithm.</p> <p>For illustrating the effectiveness of this form of equations an example is considered.</p> ER -
