Estudo e análise das vibrações no motor do carro arrancada da UEMA

Abstract

In recent years, the analyzes of the vibrations are being widely used to reduce structural vibrations or neutralization, with applications in mechanical engineering, civil, aerospace and shipbuilding. And in automobiles, the largest sources of vibration and noise are produced by forces due to combustion and mechanical forces. These forces occur in a wide frequency range and are passed to the external surface of the motor through multiple paths; one mechanism is through the piston - rod - crankshaft - the engine block. As a result of the action of these forces, the engine outer surfaces are subjected to vibrations of various amplitudes. For analyzing the operating status of any equipment, shall be measured and recorded vibrations at each of the ends or support, with the aid of sensors, and programming Arduino board. This article aims to study and analyze the vibrations obtained in experiments in the car "rush" of UEMA. Waiting with it determine and meet the main excitatory sources of vibration in a car engine so that we can reduce the vibrations of larger amplitudes
