Summary:The contact mechanism for a quartz-crystal tuning-fork tactile sensor has been investigated both theoretically and experimentally. We assume that the L-shaped right half of a quartz-crystal tuning fork is described by Sezawa's model and the torsion spring model. The frequency of the tuning-fork tactile sensor is analyzed by considering the lateral clamping force of an acrylic resin case and Winkler's foundation of the object in contact. The calculations are performed under two boundary conditions at one end of the bar which corresponds to the center of the base. Five metals (brass, copper, aluminum, stainless steel, and iron) are investigated in the present experiment. The calculated results are in reasonable agreement with the experimental ones.
