Annotation: Currently, the use of a high-energy method of plastic deformation of metal using the energy of a high-voltage pulsed discharge in a liquid has been developed (the electrohydraulic effect), and on its basis electrohydraulic processing.The article describes a method for restoring piston pins of internal combustion engines through the use of an electro-hydraulic distribution method. The degree of influence of the electrical parameters of this process on the amount of deformation of the piston pins is determined depending on the product material used. The optimal recovery technology was selected and the optimal parameters of the electrohydraulic distribution process were determined.Technical requirements for the restoration of piston pins have been developed. A technological unit for distributing piston pins has been designed. The main technical characteristics of the parameters of the electric discharge device of the installation have been determined. The calculation method was used to determine the modes and parameters of the process of electrohydraulic expansion of piston pins while maintaining their fatigue life, static strength and wear resistance.
Keywords: restoration, piston pin, electrohydraulic expansion, wear, repair size, electric discharge, plastic deformation of metal, electromagnetic energy, energy of explosives.
