MECHANICAL ENGINEERING

Il corso si propone di formare gli allievi ingegneri alla modellazione cinematica e dinamica dei principali sistemi meccanici e delle macchine, lo studio delle vibrazioni di sistemi ad uno o più gradi di libertà, lo studio dei sistemi meccanici robotici.

Durante il corso verranno svolte delle esercitazioni numeriche al computer.

Lezioni frontali per 2/3 delle lezioni del corso;

Esercitazioni numeriche per 1/3 delle lezioni del corso.

Conoscenza della Analisi I, Fisica I e Fisica matematica.

The exam consists of:

- a written test consisting in the study of a mechanical system with the methods studied during the course;

- an oral test based on knowledge of the contents, the relevance of the answers to the questions asked, the ownership of technical language, the ability to make connections between the contents of the program.

The final evaluation will be determined taking into account the evaluation of the two tests.

The candidate describes the dynamics of a simple mechanical model

The candidate describes a forced and non-forced mass-spring-damper system

The candidate writes the equations of the kinematics of a simple mechanical system (four bar linkage, slider cranck etc.)

The candidate describes the wear

the candidate writes the friction with an example

The candidate describes the eq of E-L and N-E
