Ergonomic Optimization of Work Cell of Manufacturing Systems in Virtual Environment

The paper deals with the development of a methodology for studying, in a virtual environment, the ergonomics of a work cell in an automotive manufacturing system. The methodology is based on the use of digital human models and virtual reality techniques in order to simulate, in a virtual environment, the human performances during the execution of assembly operations. The objective is to define the optimum combination of those geometry features influencing human postures during assembly operation in a work cell. In the demanding global marketplace, ensuring that human factors are comprehensively addressed is becoming an increasingly important aspect of design. Manufacturers have to design work cells that conform to all relevant Health and Safety standards. The proposed methodology can assist the designer to evaluate the performance of workers in a workplace before it has been realized. In the paper is analyzed a case study proposed by COMAU, a global supplier of industrial automation systems for the automotive manufacturing sector and a global provider of full maintenance services. The study and all the virtual simulations have been carried out in the Virtual Reality Laboratory of the Competence Regional Center for the qualification of the transportation systems (CRdC “Trasporti” - www.centrodicompetenzatrasporti.unina.it), that has been founded by Campania region with the aim of delivering advanced services and introducing new technologies into local companies operating in the field of transport.
