Abstract: To make the handle contact surface shape design have better physiological and mechanical basis for improving the man-machine performance of handle,160 samples were subjected to palm tenderness tolerance test based on the pain perception characteristics.The tenderness tolerance data was used as the external load,and the energy optimization model was applied to preliminarily design the man-machine shape of the handle contact surface.The bone surface-oriented surface deformation technology and Dexmo hand motion capture device were used to deform the standard static surface,and the handle form design was implemented.The experimental and evaluation results showed that the new program had a larger working contact area,higher subjective and objective comfort,and a single hand weight capacity was significantly improved.Man-machine shape design method of handle contact surface based on pain tenderness tolerance provided a more scientific basis for shape design of handle.

Key words: tenderness tolerance, contact surface man-machine shape design, ergonomics, handle design
