| Summary: | The widespread use of flat articulated four-link mechanisms
in various automatic devices and devices requires the further
development of automated kinematic synthesis methods, which,
based on modern mathematical approaches, will reduce the
required amount of a priori information and obtain an exact
solution. The approach of the best quadratic approximation of
functions used in the article made it possible to formulate both the
optimality criterion and the conditions for its achievement on the
basis of the equation of closure of a vector contour.
The analysis of the model showed that on its basis it is possible to
evaluate the presence of singular positions of the links at which
a spontaneous change in the law of motion of the output link
is possible. A numerical experiment in the MathCAD package
made it possible to verify the synthesis methodology based on
the results of solving the kinematic analysis problem and the
graphical representation of the connecting rod curves. |
