The document summarizes research aimed at validating and improving the ISO 2631-1 standard method for evaluating discomfort from whole-body vibration. The researchers conducted field and laboratory studies to determine if the standard method accurately predicts discomfort and identify areas for improvement. Their findings showed that measuring the three translational seat axes using root mean square averaging provides a valid prediction of discomfort. They recommend simplifying the standard's guidance to focus on these measurements and developing methods to optimize multiplying factors across different work environments.
