Modern Methods of Constructional and Strength Calculations (FSI-GMK-K)

Academic year 2020/2021
Supervisor: prof. Dr. Ing. Jiří Marek, Ph.D., DBA  
Supervising institute: ÚVSSR all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Prerequisites:
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.
Course contents:
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.
Teaching methods and criteria:
The course is taught through exercises which are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
Credit: Attendance at exercises and lessons, making a simulation model of a production system.
Examination: written and oral examination.
Controlled participation in lessons:
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.

Type of course unit:
    Guided consultation in combined form of studies  1 × 17 hrs. compulsory
