Experimental Estimation of Material Uncertainty of Composite Beam Using Hall Effect Sensor

Abstract

This paper aims at the experimental analysis of composite box beam to estimate the material uncertainty. The deflection parameter has been considered for analyzing the uncertainties present in the material. The composite box beam is like a cantilever beam, where one end is fixed, and at the free end, the load is applied. In a previous study, free end deflection has been calculated using Dial Gauges whose stylus will make point contact with proposed setup. But due to this contact, it will create instrumental errors or manual errors during experimentation. To avoid such situation, the non-contact device called as Hall Effect Sensor has been developed which is the electronic device, and it works on the electromagnetic field. If the magnet comes in front of the sensor, it creates a magnetic field between them. The change in voltage or field is calibrated in terms of deflection of the beam. The output of this sensor is given to another electronic device named as Arduino (Uno) will give desired output only. In this paper, experimentation has been carried out on four composite box beams which have been manufactured by the same process to find the material uncertainties and this has been analyzed by considering the deflection parameter.
