Shrnutí Tato práce představuje sadu nově vyvinutých nástrojů implementovatelných do komplexních kódů pro simulaci spalovacích motorů pro zajištění výpočtů týkajících se vysokotlaké části termodynamického cyklu čtyřdobého zážehového motoru. Tento více-zónový simulační nástroj pracuje na základě jednoduché kvazi-dimenzionální metody reflektující reálnou geometrii spalovacího prostoru a používá specifický přístup k popisu chemické transformace složek. V případech abnormálně rychlých chemických reakcí je klasické kinetické schéma adaptivně kombinováno s flexibilní metodou chemické rovnováhy pro zl

Abstract:
This thesis deals with the influence of changes in cutting parameters and tool geometry on residual stress inside the material. I examine the influence by deep drilling. Changing the cutting parameters concerns the alteration of the tool feed and the pressure of the coolant during the process. The influence of tool geometry is studied by using two different single edge cannon drills. The research was realized in cooperation with Bosch Diesel Ltd. The theoretical part includes a description of the injection system, in which a high-pressure container is contained. The high-pressure container was

Abstract:
The thesis contains theoretical analysis of drilling by twist drill focused on the step drill. The review includes description of the drill geometry, calculation of the basic parameters of drilling, including forces and process optimization. Following is manufacturing process and analysis of the monolithic step drill designed for the required hole parameters. The optimal cutting conditions are necessary to find for the correct function of the tool. The load values of the tool are accurately assessed using a piezoelectric dynamometer, thereby obtaining the overall progress of individual loads.

Abstract:
This work is focused on the stress-strain analysis of a cutting tool. At the beginning, the study of available literature and scientific articles relating the topic is carried out. The solution of stresses and strains in whole real system has been carried out based on the computational simulation using the finite element method (FEM). The work contains a detailed description of the creation of the computational model. Model of geometry of the system has been created in the SolidWorks program. Computational simulation including the solution was implemented in the ANSYS Workbench program as well
