Work

Currently, the demand for non-conventional renewable energy power systems ("green energy"), based on wind and solar power generation, dramatically increased the relevance of the problem of development and production for these powerful power accumulator complexes, including those based on lead-acid batteries. The importance of this problem is defined and the high requirements for lead, lead alloys and are manufactured shunts, the major part of the lead-acid battery. In the absence of wind or sun current issues for independent and long power supply is the development and production of high-power power accumulator complexes. These complexes can be formed on the basis of lead - calcium - tin batteries. The basis of these batteries are shunts. The aim of this work was to create experimental models of prospective structures shunts and a number of studies. The work carried out on the mechanical characteristics of the newly developed promising lead - calcium-tin alloys. The values of the elastic modulus, the proportional limit, tensile strength at break. Mechanical characteristics are obtained for the three alloys in experimental samples. It is noted that the mechanical properties are strongly influenced by: the chemical composition of alloys, casting temperature, cooling rate of the mold, fill the frequency, thickness of calorific cover mold, which changes with time due to carbon monoxide poisoning and affect the thickness of veins and shunts framework. Considerable attention in experimental studies to determine the mechanical properties of the alloys take questions change the values of the mechanical properties of the dispersion during storage and during operation of shunts. Used the technique of accelerated aging of shunts. The obtained values of the mechanical properties of alloys shunts were used in-depth theoretical studies on the statics and dynamics of specific designs promising shunts. Investigations of the stress - strain state of shunts, load limit and the values of natural frequencies and mode shapes. A number of structural grids shunts, wherein its internal arrangement of veins and other internal components. The analysis of the stress - strain states well as selected and recommended for practical application of the optimum grid design shunts, in which the maximum stress is minimal in comparison with other designs lattices. Keywords: shunt, the grid, mechanical properties, the alloy structure, stress, deformation, natural frequencies and shapes.
