Teaching Methodologies
In the theoretical classes, the expository method is used. The content is exposed through the joint use of the whiteboard and PowerPoint presentations. Discussions about the content presented are promoted.
In theoretical-practical classes, the problem-based learning method is used. Students solve in-class exercises in which they apply the contents exposed in the theoretical classes.
Learning Results
The main objective of this unit is to understand the fundamental tools for the vibration analysis of components and structures.
This course contributes primarily to the acquisition of the following specific competences by the students: learn and know to apply the dynamic analysis of mechanisms and the techniques for detecting faults in equipment’s, as well as plan and implement industrial maintenance plans.
Program
1. Introduction: elements of a vibratory system; free and forced vibration; damped and undamped vibration systems; types of damping; harmonic movement; procedure in vibration analysis.
2. Discrete systems with single degree of freedom: free or natural vibration; natural frequency of vibration; undamped vibration; damped vibration; under damping, over damping and critical damping vibration; logarithmic decrement; resonance; forced vibration; response to harmonic loads; response to periodic loads; vibration isolation and transmissibility; force transmitted to a rigid foundation; force transmitted to an elastic support; relative motion.
3. Discrete systems with multi degree of freedom: matrix formulation; the theorem of expansion; decoupling of the equations; modal analysis.
4. Experimental vibration analysis: practical examples in the laboratory of dynamic testing of machines and structures.
