Beschreibung
Zusammenfassung:	An axial force measurement apparatus measuring an axial force of a bolt member by measuring a clamping force, of a nut member threaded onto the bolt member, which is applied to fasten a structure, includes: a sensor that applies vibration to the structure through one side of the tightened nut member and obtains, on an opposite side of the nut member, a signal by the vibration that propagates through the structure and passes through the nut member; and an analyzer that analyzes the signal received from the sensor and determines the axial force of the bolt member using a difference in propagation velocity of the signal by the vibration according to the clamping force of the nut member.
