Title Experimental evaluation of uncertainty in hand-arm vibration measurements
Bibliographic information 2011, Vol.41, p.167-179. Illus. 25 ref.
Abstract The objective of this study was to investigate which factors cause uncertainty in hand-arm vibration evaluation and to what extent they contribute to the total uncertainty of the measurements. Experiments were carried out in order to evaluate separately the factors relating to instrumentation and the methods of fixing accelerometers. The experiments were performed with handles from real machines while being handheld by an operator. Findings show that the fixing method and the accelerometer behaviour are the two main sources of uncertainty. The total uncertainty of the measurements in this work, considering both instrumentation and fixing method, reaches up to 8% of the values measured. Recommendations are made for improving the reliability of the measurements.
