摘要：
The tactile perception of a surface texture originates from the scanning of a finger on the surface. This kind of sliding contact activates the mechanoreceptors located into the skin, allowing the brain to identify the object and to perceive information about the scanned surface. In this paper, a numerical model describing finger-surface scanning is introduced in order to investigate the relationship between contact induced vibrations and scanning conditions. The model takes into account finger and surface shapes, material properties, normal contact force, and scanning velocity. Model validation is provided by comparison with experimental tests. Afterwards, the model is applied to clarify the role played by contact/scanning parameters on the induced vibration. The proposed model is useful to develop a comprehensive parametrical analysis of the vibration induced in finger-surface scanning, and to investigate the influence of material and contact properties on tactile perception.
