Course detail

Computer Methods in Dynamics

FSI-RPMAcad. year: 2019/2020

The course is focused on the dynamics of mechanical systems. The lectures deal with several basic areas, such as oscillation of one and multi-degrees of freedom mechanical systems, on oscillation of flexible body, nonlinear systems and multi-body systems. The mentioned tasks will be explained in seminars, and numerical methods will be used to solve the dynamic problems.

Learning outcomes of the course unit

The students will have detailed knowledge of vibration of systems with single and several degrees of freedom. They will be able to calculate eigenfrequencies and responses of these systems with different types of excitation. They will be able to solve practical problems that can be modeled in this way. The student will have knowledge of the vibration of basic continuum bodies. They will be able to create models using finite element method and multi-body systems. The students will be able to apply the basic methods of linearization in the solution of nonlinear systems vibration.

Prerequisites

Students are expected to have the following knowledge: linear algebra, differentiation, integration, solution of differential equations, matrix arithmetic, basic programming, particular mathematical software (MATLAB), basic statistics, elasticity, fundamental principles of dynamics, formation of kinetic equations of plane motion and solution of free oscillating systems with one degree of freedom.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Seminars are focused on practical topics.

Assesment methods and criteria linked to learning outcomes

The course-unit credit is granted under the condition of active participation in seminars and gain at least 20 points of 40. The points can be obtained by elaboration of partial tasks and presentations. The gained points from the exercise is part of the final classification of the subject.
Final examination: The exam is divided into two parts. The evaluation of the exam is based on the classifications of each part. If one of the parts is graded F, the final grade of the exam is F. The content of the first part is a test, of which a maximum of 30 points can be obtained. The content of the second part is a solution of typical problems. It is possible to gain up to 30 points from this part. The form of the exam, types, number of examples or questions and details of the evaluation will be given by the lecturer during the semester.
The final evaluation is given by the sum of the points gained from the exercises and exam. To successfully complete the course, it is necessary to obtain at least 50 points, where the maximum of 100 ECTS points can be reached.

Aims

The aim of the course is to learn about linear and non-linear vibrations of one and multi degrees of freedom mechanical systems, follows with vibration of continuum, basic methods of motion equation solving process and with dynamics of multi-body systems.

Specification of controlled education, way of implementation and compensation for absences

Attendance at practical training is obligatory. Head of seminars carry out continuous monitoring of student's presence, their activities and basic knowledge. One absence can be compensated for by elaboration of substitute tasks.
