MODELING AND SIMULATION OF MECHANICAL SYSTEMS

Academic Year 2024/2025 - Teacher: PIETRO DAVIDE MADDIO

Expected Learning Outcomes

The course aims to train engineering students in the kinematic and dynamic modeling of key mechanical systems and machines, the study of vibrations in single or multi-degree-of-freedom systems, and the study of robotic mechanical systems.

During the course, computer-based numerical exercises will be conducted.

Course Structure

Lectures for 49 hours;

Numerical exercises for 30 hours.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes concerning previous statements in line with the program planned and outlined in the syllabus.

Learning Assessment

Learning Assessment Procedures

The examination consists of:

- a written test involving the analysis of a mechanical system using the methods studied during the course;

- an oral examination assessing the knowledge of the course content, the relevance of responses to posed questions, proficiency in technical language, and the ability to make connections between program contents.

The final evaluation will be determined by considering the assessment of both tests.

 
Learning assessment may also be carried out on line, should the conditions require it.

Examples of frequently asked questions and / or exercises

The student should describe:

- The dynamics of a simple mechanical model.

- A mass-spring-damper system, both forced and unforced.

- The kinematics equations for a simple mechanical system (four-bar linkage, slider-crank, etc.).

- The wear

- Friction with an example.

- Euler-Lagrange equations and Newton-Euler equations.

- The H-D parameters.

- The fundamentals of a robotic system.

- The fundamentals of a mechatronic system.
