Mathematical Determination of the Assembly Methods of the RRR Group in the Geometric Analysis of Flat Lever Mechanisms
摘要
The paper considers issues related to mathematical choice of RRR group assembly method in planar lever mechanisms. A justification for the choice of the sign of trigonometric functions of the relative angle in the structural group is given. The given reasoning allows to unambiguously choose the angle between the links within the RRR dyad.
