Resumo
The measurement of torque in threaded elements currently is an important step in
fixing of components, because knowing the torque applied can ensure the life of this
component, ensuring that the same will not be failed for lack of grip or excess. Micro
torque measurement to the control becomes more critical, Yes because working with
very low torques, until 1 N.m, It is necessary that the instrument has greater sensitivity
to be able to measure with accuracy required. The development of a micro torque
measurement system, where he studied and developed a micro torque transducer,
Since the design of the shaft and the design of the concentration of efforts, using the
help of the software of computer simulation by finite element analysis Ansys Academic,
to ensure that this work on elastic and with a uniform distribution of forces in the
specified region. After the shaft machining, was installed as sensor element four
precision strain gage, to form a wheatstone bridge, where converted to mechanical
tension due to the torque generated in electrical signal. Being possible to correlate the
mechanical deformation in ?? with the electrical signal generated in mV/V. With this
micro torque transducer mounted the metrological characterization, defined its
properties and measurement accuracy. From the statistical evaluation of the results
obtained during the tests, it was possible to quantify the uncertainty of measurement
for the transducer, that can be used in further work carried out in this equipment.
