Development of a gripping comfort evaluation method based on numerical simulations using individual hand finite element models
Year: 2023
Type: article
Abstract: In this study, three individual hand finite element models with different dimensions were developed to perform grasping simulations.The performance of the three models was assessed by comparing the simulation results with experimental results in terms of gripping posture, contact pressure, K. Hokari et al.and gripping comfort score.Results indicate that gripping comfort scores can be evaluated with sufficient precision by the grasping simulation.A contact pressure distribution dataset was then obtained by conducting grasping simulations under different conditions.Furthermore, a gripping comfort score dataset was generated by assigning the normalised contact pressures into a regression equation developed in a previous study (Hokari et al., 2019a).Consequently, gripping comfort can be evaluated more easily using a regression equation that predicts the gripping comfort score from the hand length and position of the thumb.The proposed evaluation method will allow designers to easily and quickly develop products with better gripping comfort.
