Up until now, various Active Human Body Models (AHBMs) have been developed using different anatomical references, validation data, modelling approaches and simulation software programs. Nevertheless, all these models should comply with the same validation requirements to deliver equivalent simulation results. This study focusses on the comparison of several AHBMs in different finite element software codes against the recently published experimental data for the head-neck kinematics. The main goal of such a comparison is the evaluation of the behaviour of different models when it comes to application in virtual testing procedures. Simulations were conducted based on a multi-dimensional simulation matrix varying two software codes, two muscle material models, two muscle control approaches and three existing AHBMs. Outcomes were compared to volunteer’s head centre of gravity vertical displacement trajectories resulting in the CORA evaluation rating from marginal to fair (0,281 – 0,636).
