This study mainly constructs a finite element analysis model. The temperature, energy partition and changes of FC300 gray cast iron workpiece during dry grinding are investigated. Thermal load and mechanical deformation of workpiece during grinding can leave residual stress on the surface, which has a considerable impact on the fatigue properties of the workpiece. In the experimental part, different grinding wheel speeds (1200, 900, 600, 400 rpm), workpiece speeds (1000, 3000, 5000, 10000 mm/min), and grinding depths (10, 20 mm/min) were measured μm) Changes in residual stress under conditions. A moving heat source model and a multi abrasive model are established to simplify the condition of the grinding wheel contacting the workpiece. The comparison of material residual forces measured by X-ray diffraction measurements shows that the finite element analysis model proposed in this paper has good reliability. Finally, this model is used to analyze the effects of grinding wheel speed, workpiece speed, and grinding depth on the residual stress on the workpiece surface, and to understand the possible causes of residual stress during grinding.

In the article innovative methods of surface hardening of internal surfaces of machine parts by laser and highfrequency induction heating are presented. The relevance of applying the methods of laser and induction hardening for the internal surfaces of heavily loaded parts of quarry equipment is proved. The results of modeling and calculation of thermal and electromagnetic fields under the influence of an external electromagnetic field and laser radiation beams are presented. The original design of a complex of equipment for processing the internal surfaces of suspension parts by external electromagnetic field is described. The optimal designs of inductors with magnetic circuits made of various materials are shown. The study of the structure and properties obtained on the internal surfaces of heavily loaded suspension parts of cars, line of the BelAZ company, treated according to the optimal modes of surface induction exposure is given. The developed original technology and equipment of laser surface hardening, which makes it possible to increase the wear resistance of heavily loaded parts, is described. Data on the implementation of research results at JSC “BELAZ” – the Management Company of the Holding “BELAZ-HOLDING” for processing a wide range of heavily loaded suspension parts are given.
