Course abstract

The aim of the study course is exploring the mechanism design and calculations using MathCad and Working Model program. Study course introduce in MathCad programming, creation of work sheets, simple calculations, definitions and variables, as well as graphics creation. Students are acquiring the MathCad programming and work with the finished programs. In the Working model program is learned the tools, fixtures drawing, setting of properties, formulas for determining the characteristics of body. For simulating the mechanisms in Working Model program the data export and formula composition are used.

Learning outcomes and their assessment

Knowledge - know MathCad and Working Model software applications for mechanism design - presentation of independent works.
Skills - Students know how to do the calculations necessary for mechanism design methods application in the MathCad and Working Model software environment - presentation of independent works.

Competence - ability to apply professional knowledge and skills in practical work and studies to solve different mechanism design problems - presentation of independent works.

Requirements for awarding credit points

Final mark are obtained after practical work is completed and presentation of the independent work.

Description of the organization and tasks of students’ independent work

Independent works (see course plan) is carried out according to the specified conditions. Studding unclear questions from literature. Independent works is presented after its completion.

Criteria for Evaluating Learning Outcomes

The evaluation of the independent works d final mark depends on its quality, the fulfilment of the requirements and the presentation of the works. The student obtains a successful mark if the work is presented and at least 60% of the working conditions are fulfilled.
