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 …

Estudo de um modelo teórico de uma máquina-ferramenta
A theoretical model of a machine tool is studied which takes into consideration the vibration of the workpiece and the tool in relation to the part of the structure that can be assurred to be rigid. The greatestadvantage of this study is the simplicity of its practical application. Employing the …

Construção e balanceamento de um cilindro a alta rotação
It was developed a high speed rotor modelas a basis for a further study on dynamic of gases. We have obtained a model structure consisting of two round bases (where are fixed the bearings), spaced by three small columns. This assembly has one of its ends fixed to a bench. The rotor consists of …
