In this paper there are presented some considerations regarding ball-bearings' rings construction, assembling conditions, loading capacities, new constructions of ball-bearings having other number of balls or other dimensions of them in the way to have improved loading capacities. There are also presented theoretical and experimental researches in the field of loading capacities determination and researches on materials used in ball-bearings rings construction. Is presented an installation used in experimental researches for studies on rings having thick dimensions.

In the productdesign process, mechanical systems modeling as Multibody Systems (MBS) is a modern way. The first step in this process is the structural modeling. In this paper structural analysis and also synthesis methods and related algorithms are presented. The proposed algorithm is applied for concrete cases. The method can be expanded for spatial linkages, cam mechanisms, gear mechanisms, etc

Force control for flexible link robots using neural networks is considered. The nonlinear dynamics of the robot manipulator are identified through a recurrent neural network (RNN), which is trained in an off-line manner. Inversion of the RNN-based model dynamics leads to a feedforward component. The feedback controller gains are derived from the minimization of a discrete linear quadratic cost functional, subject to the model dynamics inferred by the linearization of the neural network along the desired trajectory. Sufficient conditions for temporal gain switching bounds are provided. The proposed control scheme is employed in simulation studies on a two link rigid-flexible manipulator.
