Course detail

Modern Methods of Constructional and Strength Calculations

FSI-GMKAcad. year: 2023/2024

Students taking part in this course obtain the basic knowledge about structural analysis at application of numerical methods. At the structural analysis they learn to define creation of geometry and elements as well as to define boundary conditions, load, etc. A part of teaching is aimed at MKP possibilities and limitations integrated in the current CAD systems (Autodesk Inventor, Pro/Mechanica). At the end of the course, everything is demonstrated on the some examples from the designing practice in the company.

Entry knowledge

The expected knowledge is from the field of mechanics of rigid bodies, especially from the field of elasticity and strength. The student should be orientated in the field of machine parts and machine mechanisms. The student must know principles of numerical mathematics, especially solution principles of the system of linear equations.

Rules for evaluation and completion of the course

Credit: Attendance at exercises and lessons, making a simulation model of a production system.
Examination: written and oral examination.
Teaching is performed in dependence on the schedule at Faculty of Mechanical Engineering. The missed teaching and lessons can be compensated by means of individual consultations.

Aims

The contents of the subject are represented by obtaining the basic knowledge about limit states in design of production machines. There are applied limit states at design of production machines here. Moreover, the basic experience and skill with the ANSYS program are taught in this subject. Students become acquainted with solution principles.
Students taking part in this course obtain knowledge about the limit states in design of production machines and about structural analysis at their numerical solution.
