【Abstract】 The mathematical models of the turning pole, the image point, theequal-opposite angle rule and the centre curve with diagram-analytics was established.The problem of the kinematic synthesis of mechanisms in three and four finitely spearated of a moving plane positions in geometry of motion for computer aided design was solved, having the block diagram of program and the example of design.更多还原
