Comparison of the Results of Various Methodologies for Evaluating the Ergonomic Workload of a Worker During the Performance of a Work Task

Abstract

The article describes the analysis of a work operation on a virtual model of a production workplace. In order for the virtual workplace to correspond to reality as much as possible, 3D scanning was used to create a digital model of the part that the worker is manipulating. Tecnomatix Jack software was used to create a virtual workplace model and simulate worker movements. The operation was analyzed by four different methods, namely RULA analysis, OWAS analysis, Comfort Assessment analysis and Lower Back analysis. The results of all analyzes for the same task show that the job is not properly designed and it is necessary to propose workplace changes to eliminate the identified problems.
