Abstract
Problem. Energy saving and energy efficiency is the pressing issue for now. One way to solve this problem is the implementation of various types of systems and devices that not only fulfill the function of energy saving but are also able to generate a certain amount of energy for its further use. Such pieces of equipment that are small, have good mobility and can easily be installed, are particularly relevant. One of the types of them is a power generating step based on a conversion of kinetic energy into electrical one. Goal. Investigation of technical solution schemes for the development of the power generating steps, converting kinetic energy into electrical one and experimental testing of the chosen solution. Methodology. We used the analytical methods of research on the development and application of methods and devices for transforming the kinetic energy into electricity. Also, experimental methods of research and mathematical methods of processing experimental research were used. Results. The analysis of publications on the ways of converting various types of energy into electric power was carried out. The technical decision schemes concerning the development of the energy generating steps that transform kinetic energy into electric one were analyzed. The advantages and disadvantages of the existing schemes of the energy generating steps were explored. The chosen version of the scheme of the technical solution of the energy generating steps was experimentally investigated. The performed calculations showed, that if there are 10 such devices with the pressing number ~ 10 thousand in a day, you can receive ~ 68 kW/Year of generated power of electrical energy. Originality. We improved the method of determination of the parameters of generated electric energy during its transformation. The modes of converting kinetic energy into electric one found further development by improving the structural elements of the system. Practical value. The proposed power generating step can be used as an alternative source of electric energy in crowded places with intensive people traffic. Installing such power generating steps will lead to reduced costs on electricity.
