Most current applications of human figure models for ergonomic assessments focus on the analysis of a static posture. However, many tasks of ergonomic interest also include a dynamic component and it is left to the user to assess whether that dynamic contribution is negligible to the results of the analysis. Unfortunately, most commercial ergonomics packages do not include the capacity to perform dynamics analysis making it difficult to quantitatively justify the static assumption. In this webcast, we look at utilizing the AnyBody modeling system for quantitatively comparing a dynamic and assumed static analysis. Comparisons between low back moments and muscle forces for an asymmetric lifting task are presented.
