Objective - development of methods for determining the dynamic parameters and basic drawings vibrating platform for forming three-dimensional reinforced concrete structures containing non-linear elastic elements with asymmetric characteristic of reducing power, which will by implementing asymmetric vibrations of the working body to increase the efficiency of compaction of concrete mixtures and reduce the cost of materials and energy. Methods of research - the asymptotic method of small parameter. Established method for calculating the dynamic parameters of vibrating platforms to help you determine the value of the stiffness characteristics of the linear drive and buffer elastic elements, amplitude and asymmetric acceleration, moments of resistance to the drive shaft, the unevenness of its rotation, and engine power. Numerical calculations are constructed depending on the load amplitude and frequency, power characteristics, asymmetric acceleration. The rational working mode oscillations of the working body, allowing effectively sealed with hard concrete mixes with low cement content. The foundations of the design of asymmetric vibration pads, taking into account specific features of welding technology of metal, harmful strains of admissible stresses, as well as the work of the rubber components, anti-loosening screw connections. Developed drawings of general type, units and parts vibrating platform for forming the bulk of concrete products. Novelty of this work is to develop the theory of vibration machines with asymmetrical characteristics of the main elastic elements of the light engine of limited capacity, the development of rational methods of calculation of dynamic parameters. Scope - engineering, construction. Forecast assumptions about the development of object of study - calculation of dynamic parameters and the development of working drawings of the asymmetric vibration of pipelines, installations for vibratory piling.
