Mathematical Modeling of Machine Mechanisms

FSI-9MBOAcad. year: 2021/2022

Using multi-body software significantly reduces the time needed to develop machine mechanisms. Prototypes enable to prove and optimize vehicle properties before a real prototype is made . Engineers mastering this area are demanded on the labour market. Students in this course will be made familiar with theoretical but also practical knowledge in this field. Software ADAMS was chosen for the practical part of the course, as it is one of the most widely used software for dynamics analysis of mechanical systems.

Learning outcomes of the course unit

Students will have a clear idea of which problems are possible to solve with the multi-body software, what data are necessary, what outputs they are able to get. Students will also acquire the necessary knowledge to enable them to independently create multi-body models using software tools.

Prerequisites

Matrix theory, basic knowledge of numerical mathematics, fundamentals of technical mechanics, kinematics and dynamics.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. In the practical part of the course the student processes a project focused on the calculation of the properties of the mechanism. Students using the ADAMS software will create a model of the mechanism and perform calculations. The results are analyzed and evaluated. During the project the student consults his / her solution with the teacher.

Assesment methods and criteria linked to learning outcomes

During the examination the knowledge of the theory and its application in the project solved during the course is examined and evaluated.
The exam consists of a written part (of the test) and an oral part. Final evaluation consists of: 1. Evaluation of the project. 2. The result of the test (of the written part). 3. The result of the oral part of the exam.
