Paper Abstract

In the past, force measurements were mostly made on constant forces or slowly varying forces. If the forces being measured varied more rapidly with time, not only the sampling rate of the force measurement equipment needed to be increased, the analog filtering of the pre-amplifier must be reduced in order to obtain the true reading of the force being measured. These forces were sometimes mashed by mechanical noise if the analog filtering is reduced and this must be compensated by increasing the digital filtering of these forces. On the other hand, the digital filtering of too many samples can cause an increase in mean error which is a function of time and the mean error will be added to the gauge reading and thus, decreasing the accuracy of the gauge especially capturing the peak force in a test. We have created a technique for designing force measurement gauges that balance the sampling rates, analog and digital filtering. The results of various testing conditions are made with different sampling rates and different analog and digital filtering. These results are compared and analyzed.
