Supervising institute: | ÚST | |||
Teaching language: | Czech | |||
Aims of the course unit: | ||||
The aim of the course is to explain all the stages of simulation preparation and to give a compact view of the possibilities of computer assisted systems in the area of foundry processes. |
||||
Learning outcomes and competences: | ||||
Student will acquire the knowledge of 3D modelling of castings, definition of initial and boundary conditions of numerical simulation, evaluation of simulation results. The optimisation of gating and feeding systems is done using real castings and is performed for all foundry processes (gravity sand and die casting, high pressure die casting, investment casting, semi-solid processes). Calculation of production costs and sale price of castings together with Pacyna’s classification of castings is described. Relationships between other modules for thermo-mechanical calculation of castings are shown. The calculations are carried out with the support of modern software products. | ||||
Prerequisites: | ||||
Basic knowledge of Foundry technology, knowledge of liquid flows and heat transfer, basic computer skills | ||||
Course contents: | ||||
Due to the development of computer technology, the numerical simulation has become helpful in designing and optimising foundry processes. Mathematical simulation is aimed at the tuning of the designed technology in the phase of production preparation in order to avoid expensive experimental testing. The simulation of foundry processes connects numerical methods, physics and computer technology. It enables the study of processes during melt flow, solidification and cooling of castings. | ||||
Teaching methods and criteria: | ||||
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. | ||||
Assesment methods and criteria linked to learning outcomes: | ||||
Course – unit credit requirements-optimisation of real casting technology, participation in the lessons Exam - written and oral parts |
||||
Controlled participation in lessons: | ||||
Participation in seminars is required. An apologized absence from seminars may be compensated by individual work. | ||||
