The Biomechanical Evaluation of Biomedical Products Assembly Process

Abstract

This paper adresses the topic of assembly process evaluation using biomechanical criteria in order to assess the posture and work load of operators involved in the assembly of small plastic products. The labor activity will be recorded using a videocinematography system called Biomec which is capable to capture the human movements and map the data acquired to biomechanical parameters. A pilot study will be conducted in advance, to analyse the planes of movement and the number of cameras that will be necessery for the study. The captured image is freezed and digitalized by the software Biomec into a human model composed of wire framed segments that represent the human segments The biomechanical model is treated by Biomec in order to calculate the biomechanical parameters involved in the assembly work. The methodology of getting data is composed of the following steps: a first shot of the situation is performed in order to raise the initial problems. In sequence the relevant data is identified and it is proceeded the constrution of the biomechanical model of the human segments involved. A second shot is undertaken to treat the data using the Biomec capability in order to evaluate the stresses involved and postural constraints. The final result is the analysis of the work situation and recommendations to improve the workstation.
