• Description:
  A test method based upon total effective acceleration transmissibility (TEAT) is proposed to study the vibration isolation performance of anti-vibration gloves. The vibration transmission characteristics of three different gloves are investigated under predominantly axial vibration using the proposed method and the procedure outlined in ISO-10819 (Mechanical Vibration and Shock-Hand-Arm Vibration-Method for the Measurement and Evaluation of the Vibration Transmissibility of Gloves at the Palm of the Hand, International Standard Organization, Geneva, Switzerland, 1996). The measured data are systematically analyzed to illustrate the measurement and evaluation errors arising from misalignments of the response accelerometer within the palm-held adaptor, unintentional non-axial vibration caused by the vibration exciter and dynamics of the coupled hand-handle system. The degree of adaptor misalignment, estimated from the measured data, was observed to vary from 5.9 degrees to 59.6 degrees. Such variations could cause measurement errors in excess of 20%. The vibration transmission characteristics of selected gloves, evaluated using the proposed method, are compared with those derived from the standardized method to demonstrate the effectiveness of the TEAT approach. From the results, it is concluded that the TEAT method, based upon vector sums of both the source and response accelerations, can effectively account for the majority of the measurement errors, and yield more repeatable and reliable assessments of gloves.
