Research subject - a forming process of rational profiles of curved blades for a ground throwing mechanisms as a technique of acceleration for particles of soil, that takes into account their subsequent movement in the air; dynamic processes in oscillating machines with eccentric rotor, unbalanced exciter and asynchronous electrical drive for a building trade; the stress-strain state for cylinders under the volume forces action; dynamic processes of bodies under the action of impact and impulse loads; creep-damage processes in mechanical engineering designs. Aim of work - development of methods for parameters analysis of a rotary ground throwing mechanisms with blades of different shapes; creation of selection methods of basic parameters of oscillating technological devices; development of methods for stress-strain state analysis of the circle cylinders under the action of volume forces; post-impact and angular velocities calculations of the mass centers for particles; a solution method development for creep-damage problems of mechanical engineering designs. The results - - the search method of optimum shape of a curved blade profile is developed; the mathematical model of a soil particle movement on a rough curved blade is created; advantages of a curved optimum blade in comparison with a straight one by matching of parameters of soil particles descent are justified; strength test results for circular cylinders under the action of body forces are given; the some problems of particles motion of mixtures in the devices for their mixing and milling are considered; selection methods of basic parameters for oscillating technological devices are established; a numerical-analytical methods and software for long-term prediction of mechanical engineering designs at project stage are presented
