Estudo experimental de um excitador de vibrações

This work developed a prototype with which it's possible to study an excitator of vibrations. As structure of the model, two basic patts (loudspeaker and mechanical addition) were got which together allow us to establish the main characteristics in what concerns to the referred excitator. Built and installed the referred model, several standards were taken in order to simulate the mathematical model, already made. After this, they were found values which it was necessary to know in order can prove the data obtained theoretically. Such model has only a degree of liberty; at the sarne time results were got such as: amplitude, frequency, angle of phase-frequency, electrical connections, and so on. Essentially, to get all the standards of vibration and the moreover inherent, it was used the following: a) Photoresistor highly sensitive, able to detect displacements of the order of micra; b) Equipments to register the signals from the photoresistor; e) Equipments and additional apparatus which si mulate a behaviour, such as: amplifier, signals generator. After finished this work, the agreeable results show the feasibility of the model and method.
