dc.descriptionTo conduct a static analysis, a geometric model of the gripper was created in SolidWorks, its material (steel 45) was selected, the gripper was defined and the load applied to it, and a finite element model was created. For this purpose, the finite element method was used, which made it possible to bypass complex manual calculations of the strength of the variable cross-section gripper with the material resistance formulas. The SolidWorks Simulation software developed algebraic equations, taking into account the connections between the elements. They relate the reaction to the material property, constraint, and load. After organizing the equations into a large joint system, the stresses, displacements, equivalent strain, and safety factor of the gripper were found. Since the established minimum safety factor of the 45-steel gripper is less than the permissible one, 35HGSA steel was used for its manufacture. Its heat treatment regime is as follows: isothermal quenching at a temperature in the furnace t = 850-870 C, cooling in a mixture of potassium and sodium nitrate with t = 300 C, the exposure time in saltpeter until complete transformation into lower bainite  = 30-40 minutes, and medium tempering at t = 400 C for  = 1-1.5 hours with cooling in air, after which the final structure is formed – tempered lower bainite. After repeated calculations, the minimum safety factor became greater than the permissible one, which ensures the gripper's operability.
dc.description.abstractComputer modelling considers the stress-strain state of solids using the SolidWorks computer-aided design and engineering analysis system. The SolidWorks Simulation application predicts the behaviour of a part in a real situation. To do this, the digital model is analysed using the finite element method. The object of the study is the water pump of the cooling system of the ZAZ "Tavria" car, in which the driven pulley and impeller are pressed onto the shaft with tension. To disassemble the water pump, a puller was designed and the performance of its most critical part, the gripper, was calculated, which operates under conditions of difficult tensile and bending resistance. Therefore, it is manufactured with a safety margin of n  3 to prevent deformation during operation. At the same time, the option of violating safety precautions when disassembling the water pump with a puller was adopted – the entire load for removing its parts is taken by one gripper due to the possible skewing of the puller.
