description: The topic of the final qualifying work: "Computational study of the influence of the shape of the combustion chamber on the heat-stressed state of the piston of an automobile diesel engine".This work to the study and optimization of the combustion chamber of the piston of a diesel automobile engine. Tasks that were solved in the course of the work:1. Preparation of a three-dimensional design model of the piston;2. Calculation of the system of boundary conditions;3. Calculation of the TNDS of the piston under the calculated boundary conditions;4. Analysis of the calculation results, calculation of the values of the stock coefficients;5. TNDS calculation of variants of optimized pistons;6. Selection of the most optimal piston, among the options considered;The work was carried out on the basis of a prototype of the YaMZ 53406 diesel engine.Methods for calculating the thermal loading of diesel engine pistons were analyzed. Calculations of the working process were made. During the work, the shape of the combustion chamber was changed in order to optimize the engine piston.As a result, 4 variants of pistons with different geometric characteristics of the combustion chambers were analyzed. Three-dimensional models of the variants were built. Strength calculations and workflow calculations were performed for each of the variants. As a result, during the comparison, the optimal piston for the designed engine was selected.
