The purpose of the project is development of a complex of scientific and technical decisions concerning increase of efficiency of linear electromechanical accelerators and force impact devices of various purpose. Methods of research - mathematical modelling, computer calculations, experimental researches in laboratory conditions. Mathematical models of linear electromechanical converters of percussion action which include a complex of the interconnected electric, magnetic, mechanical and thermal processes in view of nonlinear functional dependences are developed. The certain optimum geometrical parameters of the ferromagnetic core and an armature. The expediency of cryogenic cooling of an armature is proved and the constructive circuit of the cryogenic technological converter is offered. The design of the converter of long action with a cyclic operating mode is developed at independent system of cooling. Efficiency of the induction-dynamic accelerator with the explosion-magnetic generator for additional acceleration of massive object is shown. The concept induction-pulse extinguisher speeds of massive object is proved. For ballistic laser gravimeter the induction-dynamic catapult with an electronic control system is proved. The induction-dynamic drive for atomizers of engines internal combustion is offered. The complex of percussion devices for preservation of the information on computer stores is made. The device for fast cooling biological samples with use of the linear induction-dynamic engine of step type is offered. The device of definition of efficiency of shock action is developed. Experimental researches are carried out at percussion low-cycle loading and punching of thin-walled constructions with the help of the linear electromechanical converter of shock action. Analogues are not present. Product Description popup.authors Болюх Олена Генадіївна Гончаров Євген Вікторович Кирпильова Евеліна Терентіївна popup.nrat_date 2020-04-02 Close
