Training objectives

Provide advanced numerical and experimental methods for solving vibration problems with particular reference to the automotive field.

Use of up-to-date instrumentation regarding vibration testing.
Elaborate experimental vibration data in an original and autonomous way for the localization of vibration sources and for comfort reasons.
Simulate the dynamic behavior of mechanical systems by finite element analysis and multibody analysis.


Vibration mechanics

Course programme

Advanced finite element modeling for the dynamic analysis of critical components (e.g. vehicle chassis, automotive components): theory and numerical simulation (10 h)
Experimental vibration analysis and experimental modal analysis of mechanical systems: theory and experimental testing (10 h).
Accelerated vibration life testing (environmental testing) of automotive components: theory and experimental testing (10h).

Laboratory (30h): the student will perform finite element analysis of vehicles and engine’s components by advanced FE softwares (LMS Virtual.Lab e Nastran); The student will perform the experimental modal analysis of automotive components (vehicles, doors, etc), mounts of agricultural machine, vibration test in Maserati vehicles for the resolution of comfort issues and high vibration levels.

Didactic methods

The course includes: theoretical lectures made with the aid of multimedia systems. The didactic material is uploaded before each lecture on the web platform; training and laboratory activities regarding experimental vibration testing and numerical FEM simulations on vehicles and complex mechanical systems; technical seminars and tours in companies.
Deliverables are: short technical reports related to the numerical and experimental activities; a speech of 15 minutes dealing with the presentation of a numerical or experimental techniques among those explained during the course.

Learning assessment procedures

The exam includes an oral test.
The oral exam, for testing the understanding and application of the course content, consists of two parts: a 15-minute oral speech of an experimental technique o numerical simulation among those explained in classroom; an oral test on the course contents.
The exam is passed if the score of each test is at least sufficient. The final mark is the arithmetic mean of the marks obtained in the two tests.
