Subject: DYNAMIC TESTING OF VEHICLES (A.A. 2021/2022)
Unit Dynamic Testing of Vehicles
Mechanical Engineering (lesson)
The course aims to transmit the knowledge necessary to plan, execute and analyze dynamic tests on vehicles
Mechanical and Thermal Measurements
Signals in the time domain:Classification of signals and their features: analogic and logic signals, stationary and non-stationary signals, random and deterministic signals.
Analysis in the time domain: statistical parameters Statistical parameters are introduced since they are fundamental to describe signals in time domain.
Advanced techniques for data acquisition: The basic concepts about signal acquisition are recalled and deepened. Different acquisition strategies and high-level sampling approaches are explained
Characterisation of systems in the frequency domain: spectra, power-spectra, cross-spectra, coherence function, estimation of the frequency response function
Experimental techniques for identification of mechanical systems
Lectures via the teams platform and computer labs via teams (situation linked to the COVID emergency) During the course, hands-on experiments will be conducted in the laboratory if the situation allows it).
Written exam consisting of theoretical questions and possible numerical exercises
At the end of the course the student will be able to plan and perform experimental tests. It will also be able to correctly interpret the results of tests performed by third parties, evaluating their reliability and correctness.
