To clarify static and dynamic properties in the circumferential direction of a tapered coupling joint, the relation between loading torque and relative angle of torsion between a taper shank and a taper socket is measured for Morse tapers #3, #4 and #5. Static properties such as torsional stiffness of a tapered coupling joint and maximum loading torque are strongly influenced by the contact state between the taper shank and the taper socket. Dynamic properties such as natural frequency and damping capacity are obtained from an impulsive response test of the tapered coupling joint. These properties are also influencd by the contact state between the taper shank and the taper socket.
