Simulation of the algorithms and their visualization forthe solutions to the restricted problems of the cosmic dynamics of the fourteen bodies with three rings

Chychuryn A.

Annales Universitatis Mariae Curie-Skłodowska. Sectio AI, Informatica

2011

Vol. 11, no. 1

55--65

The restricted problem of the fourteen bodies with three rings is considered. The results of the visualization and dynamic investigations with the Mathematica system are given. The equilibrium positions are found with the use of analytical, numerical and graphical possibilities of the system. The stability of the equilibrium positions is then considered. Visualization and animation techniques are used for the observations of the motion processes.

Chaotic motion of a multi-articulated tower immersed in waving fluid: numerical experiment

Uściłowska A., Kołodziej J. A.

The offshore structures, such as multi-articulated towers, manipulators working in waving fluid are more and more popular structures. Commonly they are modelled as an inverted pendulum. The motion of such tower immersed in waving fluid is under consideration. It is assumed that the tower is hinged to the seabed by the hinge with friction. The joint of tower elements is the hinge with friction, as well. Motion of tower loaded by regular wave fluid force is considered. The numerical experiment shows that the multi-potential systems may move chaotically for some parameters of the tower and the fluid.
