• Human foot motion simulation during walking

    Machines. Technologies. Materials., Vol. 13 (2019), Issue 5, pg(s) 198-201

    The ability of a person to move quickly plays an important role in the modern, constantly accelerating world. Despite the good development of the infrastructure of large cities, a significant part of its population uses underground or ground public transport, mixing daily trips on it with walking. That is the only one fact, where the importance of the process of walking in the life of modern man can be noticed. There is a new method for evaluation of therapeutical rehabilitation complex work for human lower limbs motion recovery is introduced. Simple mathematical basis and ethalon criterias for rehabilitation complex prototype efficency control are shown.

  • IMPROVEMENT OF THE BARGE HULL BY OPTIMIZATION OF ITS RIGIDITY PARAMETERS

    Trans Motauto World, Vol. 1 (2016), Issue 1, pg(s) 36-39

    The article discusses optimization of barge hull by decreasing of its mass parameters by changing of thickness of the plates. The fish-feeding barges are usually used in calm water and in this case it is possible to consider only static loads applied on the barge hull.

    There are many calculation methods for determining stress and deflections in the thin plates. A lot of them are using uniformly distributed load and constant thickness of the plate. In real conditions, a hydrostatic pressure is applied on the barge hull. In this research, we consider a calculation method of thin plates taking into account variable thickness of the plates and non-uniformly load. In addition, we try to show by experiments and FEM analysis the possibility to use variable thickness of barge hull in building of fish-feeding barges.
