Application of the method A.B. Draghilev to the calculation of the kinematics and animation
spatial mechanisms developed prof.A.B.Ivanov, that
develops method A.B. Draghilev to solve practical problems.
Their development, with detailed explanations,
he published on the site
http://forum.exponenta.ru/viewtopic.php?t=12842
The following examples are taken from this site and transferred from Maple in the programming environment SMath Studio.
A huge thanks to Alexei Ivanov, who gave me great help in the study the method of A.B .Draghilev.

Animation curve, which is defined implicitly
Each loop equation "cam"-an implicit function F (x, y) = 0

The line of intersection of the torus and sphere(Villarceau circles)
This example is taken from an article by Дубанов А.А. :Численно-аналитическое

Cardan Mechanism.The axes of rotation intersect at an angle of 45 degrees
The same mechanism with spherical linkages
These linkages have the property that
every link in the system rotates about the same fixed point. Thus, trajectories of
points in each link lie on concentric spheres with this point as the center. Only the
revolute joint is compatible with this rotational movement and its axis must pass
through the fixed point.

RSCRmod.sm The RSCR spatial mechanism.
The calculation is borrowed from the publication of Alexey Ivanov

Delta0C.smz In the above animation three links that support the lower platform is a simplified and
presented in the form of red rods. Actually used parallelograms (pantographs), where top and
bottom mounted universal (cardan) joints. Each universal joint implemented using Three
revolute joints . The axis of the middle joints lies in the plane of the parallelogram, and
axis external joints perpendicular to this plane. Animation of this design is shown below.

A mechanisms similar to slider crank mechanism
These mechanisms are shown Alexey B. Ivanov on the website

Thanks Ber7 for your repost/new animations. Some don't work in Smath 5346,
so what. Animation is a very nice feature from Smath.
