Abstract
AbstractExoskeletons are currently introduced for several industrial applications, but in many cases the efficiency of such devices in supporting heavy physical work has not been fully proved yet. Biomechanical simulation could considerably contribute to determining the efficiency of exoskeletons in various use cases with different user populations. In this paper we present an approach to extent laboratory and field studies by using the software AnyBody Modelling System. The biomechanical simulation is applied to the “Paexo Shoulder”, a commercial exoskeleton provided by Ottobock. Results show that the exoskeleton substantially reduces muscle activation and joint reaction forces in the shoulder and does not increase activation or forces in the lumbar spine. Comparison with laboratory measurements show very similar results. This indicates that the simulation framework could be used to evaluate changes in internal body loads as a result of wearing exoskeletons and thereby, supplements laboratory experiments and field tests during exoskeleton design and development.KeywordsMusculoskeletal modellingExoskeletonBiomechanical simulationIndustrial exoskeletonsAnyBody Modelling SystemPaexo shoulder
