Vibrations and Noise

Recommended Prerequisites

Mathematical analysis, physics, applied mechanics, strength of materials.

Teaching Methods

Classes take place in theoretical and practical scheme in which theoretical concepts are presented and applied immediately.

Schedule of vibration and noise course include the following classes:

Theoretical classes: 26h

Theoretical-practical classes: 26h

Laboratory classes: 6h.

Learning Outcomes

The vibration and noise course wants to allow:

• ability to model the dynamic behavior of real systems through simple lumped mass models;

•  ability to deduce the equations of motion of lumped mass models and obtain the integral solutions for different types of excitation;

•  knowledge of principles and fundamental international rules for the balancing of rotating parts;

•    ability to determine the dynamic response of continuous systems and simple geometry;

• knowledge of the main parameters of the noise analysis and the rules and regulations in the industrial and urban field;

 

• earn a set of basic skills that enable mastery of key concepts and allowing easy further knowledge in this topic.
