Pylyov V. Scientific fundamentals of security of long strength of pistons of speed diesel engines at use CAD

Heat-stressed condition and long strength heat-stressed of zones of pistons in view of models of operation non-stationary loading of diesel engines. Development of scientific bases and complex of techniques ensuring a specific level of long strength of pistons of high-speed diesel engines of defined technological assigning at use CAD. Application of methods of experimental researches and methods of mathematical modelling use of a gang of equivalent models. Are formulated and the positions of a system approach to projection of the piston in CAD are realized in view of a resource criterion it of strength; the complex of models for prediction of a heat-stressed condition and long strength of a set of competing constructions of pistons is developed, the methodology of their design optimization is offered; the new dates on a complex of the influencing factors on long strength of the piston are obtained. The outcomes of a scientific research are introduced in GSKBD, NTU "KhPI". An engine building.
